Gerard Butler crashed Bradley Cooper's date with Suki Waterhouse at the Wimbledon final on Sunday (7 July).
The Scottish actor, 43, sat directly beside the couple, who have been dating since meeting at the Elle Style Awards in London in February, and spent a lot of time laughing and joking with the Silver Linings Playbooks star as they watched British tennis star Andy Murray win the prestigious tournament after a battle against Novak Djokovic.
While they didn't have a moment alone at the final, the 38-year-old Oscar nominee and the 21-year-old British model enjoyed a more romantic date there on Friday (5 July) where they were spotted kissing and snuggling as they watched Andy secure a victory against Jerzy Janowicz.
A source previously revealed that Bradley and Suki's relationship is very serious and said he is besotted with the blonde beauty, who has enjoyed several romantic holidays with already.
And insider recently said: "Suki has Bradley marching to the beat of her drum. First, she clicked her fingers and he invited her to Boston, even when he was busy filming his latest movie. Then, she told him she wanted to be romanced in Paris. He immediately organised it, with no expense spared. Suki is keeping Bradley on his toes because she doesn't want him to treat her like one of his flings - she wants far more than that."
"She's ambitious and has a successful modelling career in the UK, which she is desperate to replicate in the States. And she also appeared in her first movie called Pusher last year, so she would love Bradley to introduce her to some producers and directors to expand her acting career.
"She wants to make sure that this relationship works."
Other celebrities at the Wimbledon final included Victoria Beckham, Tana Ramsay, Coleen and Wanye Rooney, and rocker Ronnie Wood.
