Selena Gomez reportedly got hot and heavy with Union J member George Shelly, after she invited the band to party with her at her hotel room.
The 'Wizards of Waverly Place' star had asked her management to book 'Union J' to perform with her at a gig in Portugal, the Daily Star reported.
Gomez, who was earlier dating Justin Bieber, invited all the boys to an after party at her hotel room.
A source has revealed that the 21-year-old singer and Shelley were reportedly "all over each other" and things got "very heated" between them.
The 20-year-old boyband member also missed his flight back to London, as he arrived separately from his bandmates.
Shelley was earlier rumoured to be romantically involved with Little Mix's Jesy Nelson.
