WATCH: The moment Lady Gaga GRINDS on a married man!
‘Gaga feels like Bradley led her on because he was giving off all the signs that they’d become an item once he was single,' said the magazine's source.
Bradley’s marriage to wife Irina ended amid fevered rumours of his affections for Gaga, but sources close to the couple have always insisted there was no truth to any suggestions he was involved with a third party.
While Bradley allegedly almost bought Gaga a ring after his marriage split, it seems that he was overcome by cold feet.
‘He suddenly realised he was jumping into a full-blown commitment to someone else and got scared,’ says Life & Style’s source.
Lady Gaga recently was spotted getting cosy with her new man Dan Horton, but according to US reports the romance is just a clever ploy to make Bradley Cooper jealous.

'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!'
