Lindsay Lohan and Max George were spotted ''all over'' each other at a party this week.

The Wanted singer - whose friend previously claimed he had no interest in dating the 'Liz & Dick' actress despite admitting she is a ''nice girl'' earlier this week - was reportedly ''all over'' the 26-year-old actress after his band performed at the Jingle Ball in Philadelphia on Wednesday (05.12.12) and they were later spotted checking into the Liberty Hotel in Boston together in the early hours of Thursday morning (06.12.12).

An eyewitness told ''They looked like a couple. When they got back from the Jingle Ball concert, Lindsay was all over Max. They were even making out at one point!''

The troubled starlet enjoyed a night of ''partying'' alongside the 24-year-old British singer after the show despite a friend close to Max previously insisting he didn't arrange for her to be there and had no plans to date her.

The duo also reportedly spent most of yesterday (07.12.12) hanging out in New York together as they were seen leaving the nightclub PH-D at the Dream Downtown hotel in the Meatpacking District together just before 2.30am.

Max has previously defended Lindsay from the furor surrounding the scuffle between the actress and Tiffany Mitchell and denied he was the reason she allegedly attacked the fortune-teller in a New York nightclub late last month.

The 'Glad You Came' singer said: ''We were just out and there was a bit of trouble with someone in the club. But it got blown out of proportion to be honest.''
