Bearer of the biggest baby bump ever, Amber Rose, has given birth to a healthy (and presumably massive) baby boy called Sebastian!

Amber looked just about ready to pop when she turned up at the Grammys last week, so we aren't surprised to hear she has finally given birth.

The 28 year old announced the happy news tonight, saying the baby boy is 'perfect'.

Naw.

Her beau Wiz Kalifan tweeted the news earlier saying: "Happy Birthday Sebastian "The Bash" Taylor Thomaz!. Everyone welcome this perfect young man into the world."

And we just love the name, even if it will always remind us of the crab in The Little Mermaid.

Earlier this week, Amber hinted she was close to her due date when she announced that she would not be online again until after their baby's arrival.

Writing on her Twitter page, she said: "Hey Rosebuds & Rosestuds Muva won't be back on twitter until Wizbud is born I need 2 meditate & focus on our Lil boy Luv u talk soon - Muva (sic)."

The star who used to date Kanye West previously revealed that she was planning to give birth in a pool at home.

Amber said: "I don't want no medication. We take home birthing classes to teach us how to do it, and we're gonna have our midwife, and when the baby's head comes out, he's gonna be Dr. Wiz. He's gonna be the first person to touch the child. No doctors, no gloves."

Just a rather big mess, or so we imagine any way.
