Lindsay Lohan is heating things up with new 22-year-old beau Julian Cavin. The troubled starlet, 26, was spotted with the DJ at Jonny Lennon’s Funday party at GoldBar in Little Italy on Sunday. “They were acting like a couple,” says a spy. “I saw them holding hands, and at times she would rest her head on his shoulder and just act really affectionate.” Lohan was also seen dancing in the VIP section with her pal, Sophomore designer Chrissie Miller, and LiLo’s brother Michael. Also there were Cameron and Tyler Winklevoss, Jessica Stam, singer Josh Groban and DJ Cassidy. Cavin took the decks along with DJ Sinatra and rapper Asher Roth. Lohan seems to have a nose for DJs — two years ago she was linked to DJ Jus-Ske, who shares the same management as Cavin. And before that was her turbulent romance with Samantha Ronson. The sojourn with Cavin marks the sad end to Lohan’s brief relationship with The Wanted’s Max George, who admitted they’d had a brief “snog” but said last week, “She’s a lovely girl. We wish her all the best, wherever she is.”
