This star is “Flamin’ Hot.”

Eva Longoria has been soaking up the sun in Marbella, Spain, with her family this week, and she rocked a sexy black string bikini with edgy detailing on Sunday.

The 48-year-old “Desperate Housewives” star wore a black Gigi C bikini top ($130) with laser-cut triangles trimming the cups and crisscross string ties under the bust, adding the matching side-tie bottom ($110) as she played with her 5-year-old son, Santiago, in the sand.

Longoria — who is married to producer José Bastón — gave fans a close-up look at the suit on Tuesday, sharing some memories from her Spanish vacation in an Instagram post she captioned “My kind of R&R????.”

The “Flamin’ Hot” director paired her bikini with oversized gold hoop earrings and a trucker hat from her tequila brand, Casa del Sol, in the pic as she lounged on a beach chair in the snap.

Fans left plenty of fire and heart-eye emojis on her post, calling her beach look, “stunning,” “perfect,” and “sexy and hot.”

“OMG, I can only dream that in my best looking days that I would look this stunning,” one Instagram user wrote. “Props to you and your parents Eva.”

This isn’t the first time the Bastóns have enjoyed a Spanish getaway this summer, with the family also having been snapped on the beach last month as the “Tell it Like a Woman” star sported some more sexy suits.

She embraced the Barbiecore trend in a bright pink zip-front swimsuit in mid-July, going on to give her husband a passionate kiss while wearing a cheeky white asymmetrical one-piece on another beach day.

Longoria even brought the heat in a long-sleeved one-piece featuring the same tiny triangle cutouts while going for a swim.
