BRITNEY Spears stripped topless as she hit the desert for a guided horseback ride.
The Toxic popstar, 41, who is undergoing divorce proceedings with husband Sam Asghari, 29, jokingly told how she "should have gone naked" for the sweltering day out.
Britney started her group trip in a yellow floral crop top with white Daisy Duke shorts.
She accessorised with a choker necklace, huge sunglasses and a cowboy hat.
Yet as she mounted her white horse and trotted behind the instructor and another rider, she took her top off.
Britney flashed her figure on the dirt track in the desert before the group made their way into the arena area.

STICKING POINT
The Sun exclusively revealed how Britney's desire to get naked proved an issue in her split with Sam.
He is said to have grown increasingly frustrated at finding his wife walking around in the nude at home while employees were on site.
The insider told The U.S. Sun: “Sam was concerned in the beginning that Britney would walk around naked at times when they were first together.
“It really put him out of his comfort zone, especially as bodyguards or handlers would be around when she was still under the conservatorship.
“However over time it really grated on him because he had asked her to cover up when gardeners or cleaners were around.
“He got very upset that his wife would be nude for these strangers to see.
“When he challenged her about it and asked her to wear clothes, she would push back calling him uptight or saying it was none of his business.
“They had raging arguments over that.”
Sam filed for divorce from Britney on August 16 after just 14 months of marriage.
The U.S. Sun previously reported that Britney and Sam’s relationship was “a rollercoaster from the start” - and the couple did not spend their wedding night together.
