You don’t mess with a girl’s La Mer.

Influencer Alexa Losey knew something was off the moment she got home from a two-week business trip.

On a recent episode of Chloe Madison’s “The Unbothered Podcast,” Losey, 30, revealed how her “abusive” relationship unraveled after she caught her now ex-boyfriend cheating — thanks to her Ring cam.

Losey and host Madison, 28, shared some of their “craziest” romance stories during the installment, with Losey recalling a particularly distressing relationship.

She alleged that her ex was excessively controlling and never allowed her any independence, describing him as “verbally and psychologically abusive.”

Losey reached a turning point when she landed a job in New York, she explained. Her boyfriend, despite being well-off, refused to join her, claiming flights were too pricey.

While she was away, he also allegedly dodged her FaceTime calls and, in a sudden shift, seemed fine with her being alone, despite previously dictating her every move. 

The popular YouTuber revealed that, at the time, she had him tracked on Find My Friends.

She had observed him being in unfamiliar locations on several occasions when she was out of town. Finding it odd, she decided to take screenshots.

When Losey returned to Los Angeles, she sensed that something was amiss. “I walked into the house and things were just off,” Losey said. 

She added that when she found her (notoriously pricey) La Mer moisturizer, “there was dirt in it and like little fingerprints in it.”

Losey claimed the other woman “used so much of” her beloved skincare products — “girl coded” items which she was confident her partner would never have touched.

“I could tell my fragrances were kind of out of place, I was like someone has been here,” she continued, stressing, “’I knew.”

Losey requested her partner to check the recordings from the Ring camera because she suspected someone had broken in. 

However, he quickly informed her that the device hadn’t been installed yet, which she found “very weird.”

“That’s when I knew. I was like I have to get into those cameras,” she recalled. 

Losey shared that she didn’t check her then-boyfriend’s phone because, in her view, if she ever felt the “need” to read his text messages, it would signal the end of their relationship.

However, she had to access the security system since she was aware someone had entered her home.

Losey told Madison that she sat with her beau and attempted to convince him to tell the truth, but she was unsuccessful.

She continued, “Anyway, that night I knew. I woke up in the middle of the night [and] my body was like ‘go get in that security cam footage.’”

After remembering that her birthday was the password to the camera, Losey accessed the footage and found another woman had been coming to their house “like clockwork” at 9 p.m. every night she was gone.

Eerily, Losey said that the mystery visitor looked “identical” to and “just like” her.

Losey then called a friend who worked in cyber security, telling him it was “so important” he help “figure out” who the woman caught on the cam was.

Within “ten seconds,” Losey’s friend identified the woman, who, to her horror, shared a significant amount of mutual followers from their “entire friend group.”

“So they were all in on it — everybody knew! Everyone! No one told me,” she recounted. 

At that point, Losey admitted she went “crazy,” taking hundreds of Ring cam screenshots showing the woman at their house — then printing 600 and plastering them everywhere.

She said she thoroughly placed the photographic evidence in the guest room, on pillowcases, under and on top of the sheets, in “every cereal box,” and even on “the f—king toilet paper.”

“I just wanted to make sure that his mom would find it, that his friends would find it, that the cleaner would find it,” the scorned Losey noted.

And, à la Stevie Nicks in “Silver Springs,” Losey said of her revenge, “I was like ‘this will haunt you for a long time.’”

The other woman eventually tried to reach out — but Losey concluded she left her on read — and her cheater ex in the rearview.
