Thylane Blondeau takes a dip in the sea in Saint Tropez

Thylane Blondeau hit the beach in Saint Tropez on Thursday, flaunting her previous title as ‘the most beautiful girl in the world’ in a skimpy two-piece.

The former child model, now 20, frolicked in the surf before kicking back at Club 55.

The French designer donned a lavender bikini top and cream bottoms, taking to the sea in the sunshine and slicking her dark locks back from her tanned features.

She looked sensational as she flaunted her taut midriff and leggy pins.

She wore chunky shades for her dip and gold jewelry – joined by her boyfriend as they waded amid the waves.

He wore grey swimming shorts and tied his dark locks back in a bun.

The model was previously in a relationship with French DJ, Milane Meritte, but the pair separated last year.

Thylane is the daughter of football player Patrick Blondeau, and earned the ‘most beautiful girl in the world’ title after she began modelling as a child. 

When she was just four years old, she walked the runway for Jean-Paul Gaultier.

Last September, Thylane was in Italy for Milan Fashion Week, walking the catwalk for the fashion brand BYBLOS.

The front row was packed with Italian celebrities and the model strutted her stuff in a sporty ensemble by the brand.   

That same month, she also announced that she was launching her own fashion brand. 

Thylane is now a brand ambassador for L’Oréal, and has been named the face of a perfume by French designer, Lolita Lempicka.

She has also appeared in Dolce & Gabbana’s Spring 2017 campaign alongside Zendaya, Lucky Blue Smith, and Presley Gerber.
