Sienna Miller, 40, showed off her sensational figure in a tiny white bikini as she enjoyed the St Tropez break.
She was joined by her younger beau Oli Green, 25, for the romantic break away.
The pair were pictured absorbing the sun and loving one another’s company on the Eden Roc hotel.
Sienna looked incredible within the skimpy bikini, showing off her taut abs and bronzed tan.
She accessorised with sunglasses and a crochet bucket hat, which shielded her from the warmth.
Meanwhile, Oli showed off his tan, stripping right down to a pair of navy swim shorts for the occasion.
Sienna first went public along with her latest relationship in February and the lovebirds were pictured packing on the PDA at Wimbledon.
