Lindsay Lohan's new lover Calum Best was barred from a VIP nightclub area after security failed to recognize him.
The womanizing model - son of late soccer legend George Best - was partying with Lindsay at Aura nightclub in the Bahamas on Friday when he visited the bathroom.
Calum tried to get back into the VIP section on his return, but was stopped by security.
An onlooker revealed Calum kicked up a fuss and insisted he was with Lindsay, but was still refused entry.
A source told Us Weekly magazine: "Best was telling the guard, 'Wait - I really want to make this point.' Eventually Lindsay sent someone from her group to come to his rescue. They came and got him. Best gave an, 'I told you so' look to the guard."
Earlier in the night, the couple attended a Janet Jackson concert at the opening of The Cove Atlantis Hotel. As Janet performed hits including "If," Calum, 26, wrapped his arms around Lindsay, 20.
Meanwhile, Lindsay allegedly partied so hard in New York last week she was "barely able to speak."
Last Monday, she visited the Apt club at 4:30 a.m. after the Metropolitan Museum's Costume Institute Gala.
A source told the New York Daily News newspaper: "She tried to pay a security guard to have her own corner of the dance floor, but he just laughed at her. A few very well-known transvestites were also talking about a fun little bathroom trip they had with Lindsay."
The following night, Lindsay spent the evening with Calum in New York's 60 Thompson Hotel. The actress also partied at the Box nightclub and watched British band The Kooks perform at Irving Plaza last week.
A source said: "She needs to stop soon. She's running right now on adrenaline, and she's going to burn out."
