Braless Bella Thorne almost risks a wardrobe malfunction as she reveals her underboob in a floaty crop top during day at the beach

Bella Thorne inadvertently flashed her chest while enjoying a day on the beach in Miami, Flordia on Thursday.

The stunning star went without a bra while soaking up the sunshine in a pretty floral two-piece ensemble, but revealed perhaps a bit more than she'd bargained for while leaning forward in the shallow water of the sea.

The 18-year-old actress showed off much of her underboob and slender waistline in her daring floaty crop top while bending down, seemingly to pick something up from under the water.

However, she managed to avoid a complete nip-slip as she regained her composure to continue her day of fun in the sun.

Bella was joined by her older sister Dani - to whom she bears a remarkable resemblance - for the day at the beach while on vacation. 

Despite being a few years apart, Bella and her 23-year-old sister look so spookily similar, that at first glance it is hard to tell them apart.

Floral delight! Once she had regained her composure, Bella showed off her stunning ensemble and enviably slender, curvy figure while splashing in the surf

Feel flirty in florals this spring like Bella in Forever 21

When she hits red carpet events she's often spotted in designers from Mugler to Marc Jacobs, but when Bella Thorne is out and about she often sticks to high street pieces.

As Bella hit the beach here, she chose trusty Forever 21 for her red co-ordinates.

The cute set was in a bold hue and floral print that was perfect for the spring/summer season and she added a cool-girl twist to the cute look by adding a pair of white trainers - very model-esque.

We do love it when celebs wear high street because it means we can all actually afford to copy their style and with Bella's outfit choice you'll have no problems as the separates are £13 apiece! Bargain.

Florals are perfect for spring, so why stop at one new skirt? Check out the other options below to get ready for the warm season.

The top was the perfect length to show off the star's hard worked for trim tummy.

Bella is in the gym daily and it shows, as her stomach was so toned that you could see her abs.
