It's a battle of the whiny b**ches!

Drake dropped a surprise mix tape yesterday ahead of his fourth studio album, due out later this year, and the rapper reignited his feud with Tyga by taking a swipe at his maturity and comparing him to his 17-year-old girlfriend Kylie Jenner. Oh snap!

"I heard a lil lil homie talking reckless in Vibe / Quite a platform you chose, you shoulda kept it inside / Oh you tried, it's so childish calling my name on the world stage/You need to act your age and not your girl's age," he raps on his tune "6 pm in New York".

Tyga quickly responded to the diss on Twitter, but has since deleted his post. "u still a b*tch. All that sneak dissing is weak. Just pull up…" he wrote.

The Vibe interview Drizzy references in his insult was from back in October, but clearly the wound is still fresh. "I don't like Drake as a person. He's just fake to me. I like his music; you know what I'm saying? I think his music is good, but we're all different people," Tyga sniped to the mag.

Is this Biggie vs. Tupac 2.0? We doubt it, since these two are both all bark and no bite!
