According to X17-Online, the pop diva, who was recently in the news for an extreme-svelte body double pic for a perfume advert, donned a lacy see-through top and black hotpants, while she came out of the shoot in Santa Monica.
The newly divorced singer even wore a large diamond on her ring finger.
It seems that the 25-year-old has patched up with cousin and former assistant Alli Sims, as the latter was waiting in a car outside the shoot.
The two headed to a drive-in burger restaurant after the shooting was over, and later changed clothes at the Beverly Wilshire hotel before hitting a party at Winston's.
Sims has recently tried to launch her own music career through her website and rumours had been rife that she had a fall out with Spears.
