The 51-year-old ex-Changing Rooms star will feature in an upcoming campaign for Playtex after being named as the brand's new ambassador.
"When we chose Linda, we knew she was the perfect fit for the Playtex brand, as someone in her 50s who truly embodies looking and feeling fabulous," a Playtex spokesperson commented.
Barker finished third in Saturday's (February 2) Splash! final behind winner Eddie 'The Eagle' Edwards and runner-up Jake Canuso of Benidorm.
Taking to Twitter after the Tom Daley show's wrap party, Barker wrote: "Bruised & woozy. Had the best night.
"Dancing 'til gone 2 with all the dive boys. Shame they're all younger than my daughter! Including Tom."
Over 5.3m people tuned in to the Splash! final, giving the show its second-highest audience and making it the most-watched programme on Saturday night.
