Kevin Hart gave his best friend, Nick Cannon, an epic birthday gift.

Hart and Cannon have been pranking each other for some time now, but the "Central Intelligence" star took it to the next level recently. He broadcast Cannon's phone number on a digital billboard in Los Angeles and encouraged the public who need fatherhood advice to call the rapper.

"Since my brother @nickcannon decided to buy me a lama for my B Day I decided to do something nice for him as well," he wrote. "I also did some in ATL & NY….if u want any advice on fatherhood please call my BEST FRIEND @nickcannon ….I’m sure his phone has been ringing nonstop [face with tears of joy emoji] GOTCHA BACK B---H #PRANKWARS."

Hart's post received several comments, with many laughing and praising his epic prank.

"Oh this is good," Dwayne "The Rock" Johnson commented with clapping hands and face with tears of joy emoji.

"Savage clap back," Watch Anish added.

"Can’t wait till me and Kevin become real friends lol this my type prank war lol," entrepreneur GotDamnZo stated.

Cannon shared Hart's post on his Instagram Story. "My phone won't stop ringing!!! @kevinjart4real is a a--hole!!!" he wrote.

When Hart celebrated his 42nd birthday earlier this month, he received a llama as a birthday present from Cannon. He shared a video of the llama on his Instagram account when it arrived at his home.

"F--king @nickcannon Best B Day gift ever a--hole," Hart wrote.

" love you man!!! I’m having all these new kids I figured you should have a new kid too!! Welcome Lucky The Llama to the family!! #SaveTheDrama4YourLlama," Cannon commented.

Cannon welcomed four children within just a year. When City Girls rapper JT (née Jatavia Shakara Johnson) advised him in an episode of his Power 106 Los Angeles radio show to "wrap it up and protect yourself" to prevent unplanned pregnancies, Cannon made it clear that everything happened as planned.

"I'm like a seahorse out here. That's just the way I'm procreating," he jokingly said before adding, "I'm having these kids on purpose. I don't have no accident!"
