Taylor Armstrong is in Kyle Richards' corner.

A little more than a month after the The Real Housewives of Beverly Hills star admitted to recent marriage troubles with husband of 27 years Mauricio Umansky, her former costar is voicing her support for the pair.

"I love Kyle like a sister, she's been like family to me forever," Taylor exclusively told E! News Aug. 23, "and if Kyle's happy, I'm happy. I love Mo, and those girls and her family, it is everything."

In fact, Taylor believes Kyle and Mauricio—who share daughters Alexia, 27, Sophia, 23, and Portia, 15—have what it takes to weather their relationship issues. "They're going to work through it no matter what," The Real Housewives of Orange County castmember added. "Happiness all around."

Earlier this summer, Kyle opened up about her and Mauricio's marriage while shooting down rumors they were breaking up.

"Any claims regarding us divorcing are untrue," the 54-year-old wrote in a July 3 Instagram. "However, yes, we have had a rough year, the most challenging one of our marriage. But we both love and respect each other tremendously. There has been no wrongdoing on anyone's part." 

Since then, multiple Housewives star have voiced support for Kyle amid the trying times in her personal life. Last month, Erika Jayne echoed her costar's public statement by firmly denying a divorce is on the horizon ahead of RHOBH's upcoming 13th season.

"They're not splitting," the singer told Billboard. "They have had a very hard time. They've acknowledged that. And I think it's best throughout the season that she tells her own story."

Meanwhile, Garcelle Beauvais revealed in July that she had briefly texted with Kyle and she said "she's hanging in there."

And when it came to Cynthia Bailey's take on the matter, the Bravolebrity promised she'll have her Ultimate Girls Trip costar's back no matter what she decides to do in her marriage.

"I just think, at the end of the day, if it doesn't bring you peace and happiness, then you guys should really have that real conversation and go from there," Cynthia exclusively told E! News last month. "I adore Kyle. I adore Mauricio. I think that they have, from what I can tell, an amazing relationship, a beautiful family. I always root for people to work it out. But I feel like at the end of the day, whatever's going to make them both happy is what I support."
