Gwyneth Paltrow flashes taut midriff in white bra and shorts as she shares snaps with daughter Apple, 19, and son Moses, 17, from vacation in Mexico

Gwyneth Paltrow took to Instagram on Saturday to share holiday photos with her 8.3 million followers.

The 51-year-old star – who won the CFDA Fashion Award for Innovation – was a proud mum as she uploaded photos of daughter Apple, 19, and son Moses, 17.

Paltrow and husband Brad Falchuk, 52, have been enjoying their Mexican getaway all week.

In one striking snapshot, Gwyneth and her mini-me posed side by side in front of a beautiful sunset.

And in her caption, the Goop founder simply used a single Mexican flag emoji.

Paltrow looked stunning in a two-piece white look that consisted of a skimpy tube top and flowy high-waisted shorts.

Apple looked just as amazing as she modeled a flowing maxi dress with spaghetti-thin straps.

In another photo, Apple was seen alone, looking all grown up as she pulled up her blonde locks with one hand.

She sat in a wicker chair and wore the same dress as in the beach photo.

The teen, whose father is Chris Martin, looked longingly at the camera as wispy bangs framed her face.

There was also a group photo showing Paltrow's two children, along with her husband and stepchildren.

The blended family wore black, white and khaki outfits as they smiled and showed off their tans.

Falchuk shares Isabella Falchuk, 19, and Brody Falchuk, 17, from his previous marriage to Suzanne Bukinik.

Gwyneth told People that her children have been “responsible” with the freedom she has given them.

“They treated it with reverence. I've always said, 'I don't have to give you a curfew unless you give me a reason to give you a curfew,' something like that.”

She continued, “They are responsible and have never done anything crazy.”

The proud mother added: “I really enjoyed having teenagers. I mean, Apple is in her last year of teen years now, which I think is so crazy that she'll be turning 20 on her next birthday. I don't know exactly how that happened.'
