Wiz Khalifa hates it when his baby son cries.

The 25-year-old rapper and his model fiancée Amber Rose welcomed their son Sebastian, nicknamed ‘Bash’ a month ago.

But although Bash is doing “great”, the tot’s wailing is tearing on Wiz’s heartstrings.

"Bash is great, man, he's awesome. He's eating on time, he's taking good poops, like a good baby should. He's been good,” he told MTV’s RapFix Live.

"The hardest thing for me is just when he cries. I want to give him everything just so he stops crying. You never want your baby to cry.”

Wiz and Amber are clearly relishing parenthood after announcing her pregnancy at the MTV VMAs last year.

Now, Amber is planning to get back in shape and spend a little time on herself, according to her beau.

“She's doing great,” Wiz declared. “She's tanning; she just bought some rollerblades. She's about to start skating around outside and get her body back together.”

Meanwhile, the rapper has wasted no time in returning to his busy music career.

On Thursday, he will release the video for his new single Let It Go, featuring Akon, which can be found on his O.N.I.F.C. album.

Luckily, his newborn son is fine with him hitting the music trail again, according to Wiz.

"He's letting me get back to work, so it's good,” the rapper laughed.

“We talked about that the other day; he let me know it was cool.”

Amber and Wiz, real name Cameron Jibril Thomaz, began dating in early 2011 before getting engaged on March 1 last year.
