Move over Bieber! It looks like Selena Gomez is cozying up to a new boy toy, George Shelley from Union J.

According to Perez Hilton, Selena had a sexy sleepover with George after Union J opened up her concert in Lisbon on September 11th.

After the show, she invited George and the other Union J boys to a private after party in her hotel room where they spent an evening drinking and dancing.

A source revealed, “She invited all the Union J boys and some other members of her entourage to her room and they had a great time drinking and dancing. Selena and George were all over each other and things got very heated. Everyone else left at 2:00am so they were able to spend the night together.”

The “Come and Get It” singer knows how to go after what she wants, and the pair have been pretty flirty over the last couple months. Hollywood Life reports that George revealed his crush on Selena in February and Selena responded with a video message asking him to call her when she was in London.

After exchanging some text messages, George, 20, revealed that he hoped to plan a romantic rendezvous with the 21-year-old starlet after Union J opened her concert in Portugal.
