Reese Witherspoon sizzles in a white one-piece swimsuit on luxurious Mexican beach vacation

Reese Witherspoon stunned in a one-piece swimsuit during a holiday getaway south of the border.

The “Legally Blonde” star was grinning ear to ear Tuesday as she soaked up some sun in Los Cabos, Mexico, wearing a white bathing suit with a wide-brimmed sun hat.

Witherspoon kept her beachy look simple with a bracelet, stacked necklaces and a makeup-free complexion.

At another point, the mother of three rocked a simple white cover-up with a drink in hand.

The 47-year-old actress’ warm weather vacation comes after she spent Christmas with her children.

“Merry Christmas from my family to Yours ❤️💫🎄,” Witherspoon wrote via Instagram Monday, sharing a carousel of snaps from her festive gathering.

The newly single actress filed for divorce from Jim Toth in April after 12 years of marriage.

The month before, Witherspoon wrote in a since-deleted Instagram post that she and Toth “enjoyed so many wonderful years together and are moving forward with deep love, kindness, and mutual respect for everything we have created together.”

The Oscar winner shares 11-year-old son Tennessee with the talent agent. She also shares daughter Ava, 24, and son Deacon, 20, with ex-husband Ryan Phillippe.

The A-lister has not been romantically linked to anyone since her recent split — at least not accurately.

Last month, rumors circulated that Kevin Costner was “romancing” Witherspoon after a social media poll claimed the two had something going on.

“POLL OF THE DAY: Kevin Costner is rumored to be romancing Reese Witherspoon. Do you love this new couple?” a tweet posted by “Naughty but Nice” podcast host Rob Shuter read.

However, Page Six exclusively confirmed that those rumors were false.

“This story is completely fabricated and not true,” Witherspoon’s rep told us.
