If there’s anyone who understands what the pressure of the Masters might mean for Rory McIlroy, it’s Caroline Wozniacki.

Wozniacki, the pro tennis star, is engaged to McIlroy, who has never won at Augusta. Oh, he did have one of the worst collapses in Masters history in 2011, when he went into the final round leading with a score of minus-12. He imploded with an 80 on Sunday to finish fourth.

This year, McIlroy seems pretty stress-free going into Augusta. During the Par 3 tournament on Wednesday, Wozniacki caddied for her hubby-to-be. And even showed off a new ‘do in the process (consider your slime green hair put on notice, Katy Perry).

High five!!
