Gwyneth Paltrow, 49, strips off and drenches herself in water as she bathes in milk

Gwyneth Paltrow, 49, has treated her followers to some scantily-clad snaps as she took to Instagram to promote her new Goop skincare product. 

The Oscar winner posted a selfie of herself appearing topless wearing just glasses while lying down.

In a separate clip, Gwyneth shared some behind the scenes footage from the photoshoot for GOOPGLOW Dark Spot Exfoliating Sleep Milk. 

Gwyneth sat in a bath of milk wearing a strapless white bikini while. As she sat up, a friend poured a giant bucket of water over her head.

In another post, Gwyneth wrote: “The team made me take a milk bath and I didn’t hate it.”
