She is the proud mother of three children.

And just 16 months after her latest arrival, son Isiah, the actress and singer, took to her Instagram page to show off her hunky physique as a fashion ambassador for Fashion Nova.

For her latest ad campaign for the American fashion retailer’s new arrivals, Milian wore a skimpy white bikini during a family trip to the Italian island of Sardinia.

Multi-talented entertainer that she is, Milian hosted a runway-style fashion show for one video, which began with her stepping out of a sliding glass door.

“Uno Dos Thres 4-5-6-7 @FashionNova #fashionnova #fashionnovapartner #newarrivals,” the 40-year-old shared in the caption, adding a little excitement to her first appearance, which saw her stripping down in a little white one sarongs

Now clad only in Fashion Nova’s two-piece swimsuit, the Love Don’t Cost A Thing star struck a series of poses in both a beach towel and just a bikini.
