Famed makeup guru Billy B — is considered one of the best in the business and has been venting to pals that a former underling, now Gaga’s makeup artist, has been taking credit for his signature “look.”

“Billy was responsible for Gaga’s ever-changing image and her ‘glam’ looks. He showed her that she could be beautiful and didn’t have to hide behind masks,” one source who has worked with him tells Confidenti@l.

But the battle started after Gaga moved on to makeup artist Tara Savelo (near r.), who happens to be Billy B’s former assistant. When E! Online posted a story crediting her with the singer’s most famous looks, Billy (r.) was “hurt,” he tells us. Making matters worse, Gaga poached Savelo after meeting her on the set of the “Bad Romance” video, for which Billy did the makeup.

“By Tara positioning herself (for supposedly cultivating those looks), she’s insinuating those were her creations,” Billy tells us. “For people to read that she’s responsible for the look, no. This is all I’ve got, and I’m proud of it. This is not gonna happen, girl.”

Billy adds that Savelo is no longer working for Gaga.

Tara isn't doing her makeup doe.

It was reported a while back that Billy B was ditched because his busy schedule didn't allow for being Gaga's full time make up artist so his then assistant Tara took over. Similar to how Nicola Formichetti was replaced by Brandon Maxwell.

If you're not going to commit majority of the time to an artist, don't be surprised when you're ditched. Maybe he should have committed to less episodes of RuPaul's Drag Race.

That said, Gaga's new makeup artist is Sarah is better than both.

S'okay, Billy B -- karma came for ha.

Also, what exactly is Gaga's signature make up look? Her make up is ever evolving, like her hair.
