Lady GaGa's a Britt angry

The singer has had words with her boyfriend Taylor Kinney's ex after she wouldn't stop hounding them.

Since she started dating Kinney, the Vampire Diaries actor has been receiving hundreds of angry phone calls from former girlfriend Brittany Sackett.

GaGa finally read the riot act a couple of weeks ago during a weekend in Vegas when her romantic meal-for-two was interrupted several times.

A source said: "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.

"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."

That's putting it mildly. GaGa has spent the past two weeks introducing her new bloke to all her bedroom repertoire.

Surprised that only took her 14 days.
