Gaga recently had strong words with her new boyfriend, asking him to stop taking phone calls from his ex-girlfriend.
Gaga snapped during a romantic meal with ‘Vampire Diaries’ actor Taylor Kinney – who she first met on the set of her ‘You and I’ video three months ago – after they were disturbed several times by angry phone calls from his former girl, Brittany Sackett.
“Brittany is extremely jealous. But as crazy as Gaga is, she’s also a very good person and has a real sense of womanhood and looking out for other women,” Contactmusic quoted a source as telling The Sun.
“She and Taylor only started dating a few weeks ago, despite feeling sparks when they met on the set of her ‘You and I’ video almost three months ago because it was the right thing to do. But she wants to be left alone to enjoy her new relationship now,” the source added.
Gaga has already been warned off Taylor by pals after Sackett – an estate agent from San Diego – claimed she was still in a relationship with the actor when he first started dating Gaga.
Ohh, that’s feisty, Gaga!
