Nicole Richie and Melanie Brown had to double check their assets weren't popping out for the cameras at a charity event at the weekend.

The Spice gal was forced to adjust her dress to ensure that her impressive cleavage was on show without any nipple-slips.

Meanwhile, wearing a revealing sparkly number, The Simple Life star made sure she didn't have a wardrobe malfunction by keeping a close eye on her newly-acquired curves.

The new mum seems to have kept her post-pregnancy boobs as her previously non-existent chest looked bustier than ever.

Both stars were out with their breast pals for the 30th anniversary Carousel of Hope Ball in L.A for childhood diabetes.
