Crystal Palace will play in the Premier League next season after Kevin Phillips' extra-time penalty earned a 1-0 win over Watford in the Championship play-off final.
After 90 minutes had failed to produce a goal at Wembley, Palace eventually scored the winner their second-half dominance deserved just before the halfway point in extra-time, when Manchester United-bound Wilfried Zaha earned a spot-kick, which was ruthlessly dispatched by substitute Phillips.
The victory will see Ian Holloway's side return to the top flight after an eight-year absence and bank an estimated ?120million. Gianfranco Zola's Watford, who were never allowed to get into their stride, must try again next season after narrowly missing out on automatic promotion on the final day of the season.
The two previous Championship meetings between the sides produced nine goals but the first half at Wembley was a tight and tense affair, with neither goalkeeper tested.
Watford dangerman Matej Vydra was given a sight of goal on 33 minutes when neat interplay around the edge of the box saw the ball break for the Championship Player of the Year. But as he looked to bend a shot with his right instep, Damien Delaney threw himself across to get in a splendid block.
The challenge left Vydra with an ankle knock and the Czech forward was unable to continue after half-time, with Spaniard Alex Geijo coming off the bench to start the second half.
The game's first real opportunity came just before the hour mark, when Aaron Wilbraham was played in behind the Watford defence. The Palace forward, though, was eventually reined in by the chasing centre-halves, who were allowed to get goal-side and block when Wilbraham tried to cut inside and shoot.
Manuel Almunia was finally tested in the 65th minute, when the former Arsenal goalkeeper made a fine block to keep out substitute Stuart O'Keefe's firm drive after good hold-up play by Zaha.
From the resulting corner, Almunia was forced to get down low again when no one in the Watford defence took responsibility for clearing a bouncing ball, gifting an opportunity to Wilbraham. The goalkeeper, though, sprang from his line to smother the Palace striker's shot.
With Palace in the ascendancy, Holloway sent on Phillips for the last quarter, and the veteran forward was soon involved in the 72nd minute. Zaha's deep cross was nodded back by Phillips to Owen Garvan, but his shot drifted wide of the far post.
Garvan did find the target with eight minutes remaining with a volley after a brilliant touch and spin in the box, but Almunia was well positioned to make the catch, just as he was two minutes later when Wilbraham created a yard of space but his shot was blocked by the keeper's left foot.
Palace tested Almunia once more in added time, when Mile Jedinak headed a corner towards goal but the Watford stopper sprang to his left to make a diving catch.
After remaining untested during normal time, Palace keeper Julian Speroni made a wonderful save early in extra-time when he dived to his left at the feet of Troy Deeney to deny the Watford striker a tap in from two yards. Speroni then stood firm to hold Cristian Battocchio's swerving drive from 25 yards.
The breakthrough finally arrived in the 105th minute. Zaha's trickery fooled Marco Cassetti, who was tempted into a challenge that sent the Palace winger crashing to the Wembley turf. Phillips took the spot-kick and smashed the ball into the top corner beyond the dive of Almunia.
Watford pressed late on and Palace were thankful for two interventions by defender Joel Ward, the second of which was a header off the line to keep out Fernando Forestieri's effort.
After the nervous afternoon at Wembley, Holloway told Sky Sports: "I am so proud of these [players]. I am so proud of the club. We are in the Premier League, so God help us."
Meanwhile, defeated Watford boss Zola was in no doubt about where the game was won, as he said: "They had a player like Zaha, who was on a different level and made the difference.
The 25-year-old twice finished clinically in the first half at Hampden Park to set Celtic on the way to a 3-0 Scottish Cup final win.
The impressive victory rounded off a memorable season for the SPL champions, whose exploits in reaching the last 16 of the Champions League proved the highlight.
And Hooper added a further personal achievement as his goals took him through the 30 mark for the season.
"It was a great win in the end and we're delighted with the double," the Englishman told Celtic's official website.
"This, getting to the last 16, winning the league, and scoring 31 goals, I'm at the top of my career.
"At the start of the season my aim was to beat last year's goals total and I did that two games ago. I was unlucky not to get to 20 in the league but I wanted to get past 30 overall and I managed that.
"This feels even better than the first time we won the Scottish Cup two years ago because we did this one in style.
"We've also got the league win and the Champions League run behind us as well so this has been my best season at the club.
"Playing like that, like we did at Hampden, really topped it off."
Hooper has struck up an excellent understanding with Anthony Stokes during his time at Celtic Park and the Irishman set up both of his goals in the final.
Stokes also had a hand in the third as he released Mikael Lustig to cross for Joe Ledley to power home, although not before Hooper missed a great chance for his hat-trick.
"It was great to have him playing next to me," Hooper said.
"He's a great striker and he works his socks off. He showed again how good he is at setting up goals but he was looking for one himself towards the end.
"He put the two crosses in for me and I'm glad he got the man-of-the-match award because he worked his socks off.
"My goals came from two great balls from him, one right foot and one left foot. I had a chance for a third but I completely missed it.
"Joe Ledley was there, though, and he scored. I hurt myself somehow when I missed the ball but Joe closed his eyes and thumped it. I'm joking, of course. It was a good shot."
