Source: `Justin Timberlake didn`t cheat`

The Social Network actor was rumoured to have gotten cosy with TV star Olivia Munn last month, a report in People said. But an insider dismissed the claims, telling the magazine, 'There is no truth to the reports. Olivia Munn is not that type of girl.'

Justin, 29, has been dating the Hollywood actress since 2007 and the pair was spotted out and about over the weekend looking very-much together.

The couple arrived hand-in-hand at Haze Nightclub after JT's Saturday night benefit concert at the Planet Hollywood Resort and Casino, which featured a performance by Christina Aguilera.

'They were sitting in a private area of the club,' the source said.

'Most people didn't even know they were there. They were really affectionate and really seemed to be happy.'

'Justin and Jessica are doing fine.'

Reps for Munn and Timberlake had no comment about their clients' personal lives.
