Iggy Azalea has regained her slender figure just months after welcoming her first child with a challenging "clean" diet.

The rapper took to Instagram and Twitter on Monday to show off her slim frame after becoming a mother to son Onyx in late April.

In the image, the 30 year old posed in a bright orange bikini and matching wig.

"Baby weight. Baby? Wait – this a baby waist," she captioned the snap.

When a Twitter user questioned how she managed to get back in shape so quickly, she replied, "It was realllly (sic) hard I can't lie. but I ate 'clean' the entire time, no cheating. as hard as it was mentally to not indulge in weird cravings, I knew I'd be glad afterward…"

She then revealed just how big of a bundle of joy Onyx was when she gave birth, sharing that he weighed 9.4 pounds (4.26 kilograms).

Azalea confirmed she had welcomed a baby with her 23-year-old boyfriend Playboi Carti in June, writing on social media, "I have a son. I kept waiting for the right time to say something but it feels like the more time passes the more I realize I'm always going to feel anxious to share news that giant with the world."
