'Gaga knows how to play the game. She’s dating Dan in a bid to make Bradley realise what he’s missing,' a source alleges to American publication Star.
Other sources tell the publication that Bradley, who is a reputed commitment-phobe ‘holds the key to her heart’.
'Bradley is hesitant about jumping straight away into a relationship with Gaga,' they tattle.
Other sources say Gaga is ready to move on. 'Until he stops dragging his feet and 100 per cent commits, she’s moving on with her life,' the source adds.
Talk surrounding the nature of Brad and Gaga’s relationship reached fever pitch following the duo's steamy performance of ‘Shallow’ at the Oscars in February– a performance Gaga insists was nothing more than good acting.
'[‘Shallow’] is a love song, A Star is Born is a love story,' she told Jimmy Kimmel on Jimmy Kimmel Live!. 'When you’re singing love songs, that’s what you want people to feel … I’m an artist and I guess [Bradley and I] did a good job …fooled ya!'
And with The Hangover star and his model fiancée parting ways just weeks after the show, it’s no surprise Irina’s fans are blaming Gaga for the split.
Lady Gaga has yet to respond to Star's claims.
