Nadine Coyle has reportedly dumped Jesse Metcalfe for his best friend.
The 22-year-old Girls Aloud beauty - who was recently spotted house-hunting in Los Angeles with 'Desperate Housewives' actor Jesse - is alleged to have hooked up with English musician Oli Trevena in exclusive Hollywood club Crimson.
A source said: "Jesse was at the club at the same time as Nadine and Oli, and he really wasn't pleased when he saw them. He marched over and said to Oli, 'What's going on? She's my ex!' "
Nadine - who is planning to relocate to Los Angeles in December - told 28-year-old Jesse to leave them alone, but the hunky actor refused and forced Nadine to talk to him.
The source added to Britain's Star magazine: "Jesse just wouldn't let it go.
He kept bugging Nadine, saying he needed to talk to her. She eventually gave in and dragged him to the bar, where they chatted for 20 minutes.
"After she got fed up talking to him, he followed Oli into the toilets and had words with him instead. It hasn't stopped anything though - Oli has even met Nadine's mother Lillian."
Oli, 26, who has lived in Los Angeles for the last four years, has previously been linked to British TV presenter Denise Van Outen and former S Club 7 singer Rachel Stevens. He is also close friends with singer Robbie Williams. |
