KATE Upton is a rhapsody in blue as she steals the ­limelight at a red carpet event in Florida.

The model-turned-actress, 31, wore a slinky backless dress at the Sports Illustrated Swimsuit Island bash to mark the magazine’s 60th anniversary.

And Kate was joined by the original Uptown Girl, Christie Brinkley, now 70 — who starred in the video of her ex-hubby Billy Joel’s No1 UK hit in 1983.

Kate previously called American baseball player Justin, 40, her “perfect partner” and the pair welcomed their daughter, Genevieve, a year after they wed in 2017.

She and Verlander met while working on Major League Baseball 2K12 video game in 2012 and officially started dating in January 2013.

Their relationship ended for about six months in mid-2013, but they were back together by January 2014.

In 2016, Verlander popped the question and after winning the World Series with the Houston Astros in 2017, they set off for Tuscany, Italy to get married.

The three-time cover girl is one of SI Swimsuit’s most celebrated models.

Kate made her magazine debut in 2011, when she was named Rookie of the Year.

She earned back-to-back covers immediately following her debut, in 2012 and 2013, before going on to land her third cover in 2017.

“To me, it means so much because I grew up looking at all the Sports Illustrated models and admiring all of them being from a sports fanatic family,” she said after her 2012 cover.

“I know how everyone talks about how it’s such a boost to your career, but it means a lot to me personally.”
