Tennis unknown scores with TV starlet

Mark down another ace for Ryan Sweeting.

He may be only the 532nd-ranked men’s tennis player in the world, but he’s about to be in the top 10 in the wives department if a report Thursday is true, as TV star Kaley Cuoco has reportedly agreed to marry him. US Weekly reported the engagement Thursday, citing "a source close to the couple."

"It’s only been three months but she knows Ryan is the one," the source said.

Cuoco, 27, stars in the popular CBS sitcom "The Big Bang Theory," currently the most-watched comedy on TV and recent Emmy nominee for Outstanding Comedy Series.

Neither Cuoco nor Sweeting, 26, appears to have publicly confirmed the engagement, though Cuoco was in a good mood Wednesday.
