Willing and able! Kim Kardashian's newborn son, who came into the world on Saturday, Dec. 5, has a ready-made babysitter in the form of mom's best pal, Jonathan Cheban!

The 35-year-old mom-of-two's BFF wrote a sweet congratulatory message to the happy new parents via Instagram on Sunday, Dec. 6 — not only offering his best wishes, but also his babysitting skills.

"Congrats to the most amazing parents!" Cheban, 41, wrote in a caption of a cute photo of him and North West, 2. "Congrats to my BFF and Kanye on the arrival of their baby boy.. I can't wait to babysit both of the most beautiful kids," he added.

On Monday, Dec. 7, Kardashian revealed on her website that the baby's name is Saint West.

As previously reported, Kardashian and husband Kanye West announced the birth of their second child in the early hours of Saturday morning, with a sweet picture of the two of them holding hands.

"He's here!" the happy couple captioned the shot.
