The former This Morning star, 45, took to Instagram to model a flattering blue and white one-piece as she soaked up the sun

In the ad for Garnier sun cream, Holly strutted her stuff along the sand and showed off her incredible figure. 

It comes as Holly is to relaunch her screen career 'within days' with a new lifestyle show that is already filming for a four-week run on .

Holly had a secret on-camera rehearsal for the show last week, with the company making her new programme .

The series will be a This Morning-style lifestyle show called Together and will be streamed just as This Morning winds down for the summer, with regular hosts and about to go on their breaks.

It comes after last week Holly attended Royal Ascot and had a cheeky accessory to complete her Ladies Day look as she joined a slew of stars for a day at the races.

She graced the track in an elegant all-white look, which consisted of a pleated skirt and wrap-over jacket dress from SIMKHAI.

During her day out, Holly showed off her phone case which featured the lewd phrase 'You're doing your f*****g best.' 

She added all-white accessories including an elegant wide-brimmed hat from Jane Taylor London and a £750 Aspinal midi Mayfair bag, finishing her look with a pop of ruby red lipstick.

'Off to Ascot officially here for the horses, unofficially here for the champagne and cake', Holly captioned her photo.
