Lindsay Lohan has a new boyfriend

Actress Lindsay Lohan has a new boyfriend, it has been revealed.

Lohan - who split from Riley Giles after a thanksgiving breaking in New York last month - took her latest conquest to Hollywood's exclusive Goa nightclub on Sunday.

A source revealed: "Lindsay was totally smitten with this guy. She introduced him to all her friends and said, 'This is my boyfriend, Spencer.' She kept gazing at him and they were really touchy feely."

The 21-year-old 'Mean Girls' star took her new beau out for to dinner to Il Sole on Friday, where they dined with her 14-year-old photographer friend, Austin Visschedyk.

Despite having company, Lindsay and Spencer kissed throughout the meal.

A fellow diner said: "Poor Austin looked so uncomfortable. It was definitely a case of two's company, three's a crowd."

Lohan is believed to have dumed Riley, who she met in rehab  in August this year - because he was jealous of her fame.

A source said: "She made it pretty clear when they got home that it was over. She got tired of him pouting all the time.

"It was fine when they were in Utah, just the two of them. But then they returned to Los Angeles and Lindsay was thrown back into her hectic work. His ego couldn't take it."
