Amber Rose has gone into labour.

The 29-year-old model's rapper fiance Wiz Khalifa has revealed she is due to give birth to their baby boy at any moment.

The 25-year-old 'Black & Yellow' hitmaker shared a photo of a fetal monitor with the words ''Coming soon...'' on his Instagram page on Tuesday (19.02.13).

Amber hinted she was close to her due date last week when she announced that she would not be online again until after their baby's arrival, as she wanted to focus on relaxing.

Writing on her Twitter page last Thursday (14.02.13), 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).''

She previously revealed that she was planning to give birth in a pool at home and wanted Wiz to be the first person to touch their child.

She 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.''

Amber, who initially became famous for dating Kanye West, also said she is waiting until after the birth to plan the couple's wedding.

She said: ''Being pregnant, I'm tired a lot. So to have a wedding and planning it all out and the reception - I just don't want to be sleeping when everybody's partying at our wedding.''
