Lisa Rinna didn’t mince words when she called out her “Traitors” co-star Colton Underwood, labeling him a “stalker” due to his previous restraining order controversy.

The 62-year-old actress made this bold remark on Friday in a Threads post, reacting to a fan who poked fun at Underwood for accusing her of being a traitor in the latest episode of the Peacock series.

The fan’s post featured a memorable image of Rinna from Season 7 of “The Real Housewives of Beverly Hills,” accompanied by the caption, “This is who Colton thinks he’s slick up against? GOOD LUCK BUDDY.”

Rinna didn’t hold back, replying, “Let’s talk about you being a stalker…,” directly addressing Underwood.

Later, in response to podcaster Gibson Johns, who commented on Threads about the anticipated “The Traitors” reunion, saying, “‘The Traitors’ reunion is gonna be so good,” Rinna cryptically added, “Careful what you wish for, you just might get it.”

Though the ordeal went down almost six years ago, it appears Rinna is just now finding out about it.

Days before her threads comment, Rinna left a comment under a TikTok video posted earlier this week, expressing her shock at discovering the reality star’s dark past.

“Wait what?!” she commented.

Underwood’s ex Cassie Randolph requested a restraining order against him in September 2020. The exes, who met on ABC’s “The Bachelor,” dated for less than two years before they decided to call it quits in May 2020.

According to legal documents previously obtained by Page Six, she accused the former athlete of stalking and harassing her with “unsettling” text messages and claimed he even went as far as planting a tracking device on her car.

Days later, a judge signed off on the temporary restraining order request and Underwood, now 33, was ordered to stay at least 100 yards away from Randolph.

Randolph, 30, eventually decided to drop the restraining order against Underwood with prejudice — meaning, she had no intentions to refile the request — in November 2020.

In a statement given to TMZ at the time, Underwood said that Randolph dropped the suit after the two reality stars were “able to reach a private agreement to address any of Cassie’s concerns.”

“I do not believe Cassie did anything wrong in filing for the restraining orders and also believe she acted in good faith. I appreciate everyone’s respect for privacy regarding this matter,” he told the outlet.
