Paris Hilton was reportedly refused re-entry into the People's Choice Awards.

The socialite and her boyfriend River Viiperi reportedly stepped outside during the ceremony on Wednesday (09.01.13), but security at the Nokia Theater in Los Angeles wouldn't let them back inside building.

An onlooker told the New York Daily News newspaper: ''It was super-cold outside and she didn't have a coat. She was wearing a short dress, she was on the phone going back and forth outside.''

The observer claimed the couple tried to get back in through different entrances - but had no success.

Paris and River's night had reportedly got off to a bad start because they arrived late and, because the ceremony was already underwear, were ushered to ''cheap'' seats towards the back of the room, rather than a prime spot with other celebrity guests.

The source added: ''She was so embarrassed.''

A spokesperson for the 31-year-old heiress insisted the star had no intention of going back inside but was trying to locate her car service.

And the couple didn't appear to have let the mishaps get me down.

Paris tweeted: ''Fun night with @RiverViiperi at The People's Choice Awards.''

River added: ''So Much fun at the #PeoplesChoice awards with my beautiful love @ParisHilton on my way back home now to Relax :)

''I won having the hottest and best girlfriend but they didn't have that category this year (sic)''
