Need a bigger bikini, Lisa?

Need a bigger bikini, Lisa? Ms Snowdon almost suffers a wardrobe malfunction as she hangs out on Miami beach

She's having a welcome break from her 4am alarm calls and Johnny Vaughan's bleary face every morning - so no wonder Lisa Snowdon is making the most of her current Marks and Spencer's modelling mission in Miami.

The 39-year-old model is currently taking time off from her 95.8 Capital FM breakfast show to shoot the latest M&S advert for their spring/summer collection in the more clement climate of Florida.

However, the star almost showed off more than she intended when she nearly fell out of her bikini whilst taking time out from the shoot on the beach.
