She nearly suffered a bikini malfunction yesterday - but Lisa Snowdon was almost caught out again for her second day in the Miami sun.
The 39-year-old beauty, who is taking a break from shooting the latest Marks And Spencer advertising campaign in Florida, had swapped her skimpy two dark piece of yesterday for some rather sturdier and some would argue even nicer swimwear.
The model appeared to be determined to keep her charms quite literally in check for her second day on the beach in a rather more supportive white and blue gingham swimsuit with cute little red bows.
But her plans almost went awry when it came to lying down on a sunlounger and she decided to lower bikini straps to avoid those pesky tan lines - and almost fell out of her top.

Still there: Lisa thinks better of her plan and pops her straps back up
Lisa almost exposed more than she intended yesterday too when her top rode up as she emerged from the surf.
However, she's been covered up during her shoots for the Marks And Spencer new television advert for their spring/summer collection, the reason for the star's trip out there.
The 95.8 Capital FM breakfast show host has left Johnny Vaughan back in chilly London for the assignment, which also stars Twiggy, 61, Dannii Minogue, 39, VV Brown, 27, and Ana Beatriz Barros, 28.

She Tweeted: I'm only away for a bit, filming for the new M&S ad! Be back soon on breakfast with Johnny! Miss you and him already! L x'
Johnny is soldiering on behind the mic meanwhile with stand-in host Kat Shoob while Lisa is away hard at work in the sun.

Dannii has certainly been impressed with the clothes they've been modelling so far, and Tweeted: 'Just to let you know the M&S Spring Summer collection is Uh-Mayzing!'
The girls have been filmed posing in nautical gear on yachts, in their gladrags at a fictional wedding and in swimwear whilst lounging on the beach.

The gang appear to having a fun time on the assignment, and have all been socialising during the evenings off the set - they've even brought friends and family in tow, with Dannii bringing partner Kris Smith.
However, the shoot is almost over, and Dannii jetted out from Miami today to fly back to Melbourne, with Lisa set to return to London by the weekend to resume her breakfast show duties in the capital on Monday.
