Kyle showed off her curves in a tight, sleeveless black dress in a bathroom mirror selfie.

The Real Housewives Of Beverly Hills star completed her look with black gladiator strap heels and accessorized with multiple rings, a watch and a bracelet.

Kyle had her dark hair falling past her shoulders in soft curls and enhanced her natural beauty with full makeup.

She also carried a black handbag and added a pop of color with pink nail polish and toe polish.

During a Q&A fan chat with Amazon Live on Wednesday, Kyle revealed that her split from her now-estranged husband Mauricio, 53, was “very hard.”

When asked by a fan how she and the real estate agent are doing, she answered candidly: “It’s a very loaded question.”

“You know, that was very difficult,” she continued. ‘[It’s] We play with so many people who keep an eye on us and are in the public eye.’

Despite their split, the reality TV personality, who suffered an editing error on an Instagram post earlier this week, spoke about how she enjoyed a trip to Europe with Mauricio and their children.

In her chat, Kyle explained that she and Mauricio still love each other and continue to co-parent their four daughters.

“Obviously we care a lot for each other,” she said. “You saw, here we are on vacation together.”

“I’ll share that with you now,” she said, laughing, before moving on to the next question. “Because… this is just too much to deal with right now.”

Earlier this month, the couple, who have been married for 27 years, were spotted on a luxury yacht in Italy with their four children.

The couple has daughters Alexia (27), Sophia (23) and Portia (15). Richards also has daughter Farrah, 34, with her first husband, Guraish Aldjufrie.

The Little House on the Prairie actress and the real estate magnate were married from 1988 to 1992.

Kyle and Mauricio announced they were splitting up after releasing a joint announcement in July.

In the statement, the couple responded to breakup rumors and admitted they had had a “challenging” year.

“We both love and respect each other immensely,” the statement said. “There has been no wrongdoing by anyone.”

Fans began speculating that the couple had split earlier this year and Kyle had started dating 28-year-old country singer Morgan Wade.

Kyle and Morgan denied that they were dating, but also further fueled romance rumors.

Earlier this month, they showed off their “undeniable chemistry” in Morgan’s music video for her new track “Fall In Love With Me.”
