Louis Tomlinson parties with mystery girl

One Direction band member Louis Tomlinson partied with a group of friends and spent six hours in his hotel room with a mystery girl following a nightout at a club here.

The singer, who recently split from long-term love Eleanor Calder after four years together, reportedly held a late-night party in his room, reports femalefirst.co.uk.

The 23-year-old star gave a thumbs up to waiting fans as he and the mystery woman returned to their hotel at 4.30 a.m. alongside six friends.

"Louis was having a great time at Cirque le Soir. After the club shut, they stayed behind drinking vodka. He had met four girls on the night. A fifth seemed to already know him and stuck by him. He was very protective of her.

"It was very chilled at the hotel. Louis was rolling up joints and passing them to people. He seemed to know what he was doing. He was mainly with the one girl at this point and at 6 a.m. they went to one of the rooms," a source told The Sun newspaper.

At midday the next day, Tomlinson reportedly ordered a taxi for the mystery girl with an insider claiming that the pair were "very cosy together".

"At noon he got the girl a taxi but the others had to make their own way home. She definitely seemed more important to him. They were very cosy together. He kept her apart from the other girls and his security looked out for her," the source added.
