President Donald Trump is praising Sydney Sweeney in the wake of backlash against the American actress for her controversial American Eagle advertisement.

"Sydney Sweeney, a registered Republican, has the HOTTEST ad out there," he wrote in a Truth Social post. "Go get 'em Sydney!"

The Emmy-nominated actress for roles in Euphoria and The White Lotus stars in a denim jeans advertisement, where she states: "Genes are passed down from parents to offspring, often determining traits like hair colour, personality and even eye colour. My jeans are blue."

Critics have called out the blonde, blue-haired actress's wordplay in the commercial, using "genes" instead of "jeans" - sparking debate over race and western beauty standards.

American Eagle has defended the advert and stated it was - and still is - only about the company's jeans.
