Fellow Real Housewives alum Kara Keough shared the missing persons' report on Instagram, which noted that Lindsey was last seen in the city on January 7.

She also shared that the family is "concerned" that Lindsey was "taken," as no one has been able to get ahold of her since last week.

Her caption read: "Lindsey made contact with her mom last week but has since disappeared. We need your help. There is concern that Lindsey may have been taken. Please help us find Lindz."

Tammy's other daughter Megan commented on the post, calling the situation a "nightmare."

"My heart breaks for Tammy. This is every mothers worst nightmare," another commented.

"Sending good vibes and prayers for her safe return," said a third.

"Thoughts and prayers she is found safe," echoed a fourth.

WORRIED MOM

Just days earlier, Tammy, 59, confirmed to People that she had "heard from her" daughter after she allegedly went missing in early January.

The former Bravo star revealed the pair had spoken on Saturday when Lindsey called her mother upon seeing posts online questioning her whereabouts.

"She saw all the messages on social media and called me through Facebook Messenger saying, ‘Mom, I’m okay. Leave me alone. Stop with all these messages. I don’t want to talk to anyone,’” Tammy told the publication.

The TV star also said that she pinpointed her daughter's location was in Sin City after discovering she was arrested there on New Year's Eve.

Lindsey spent a week in jail and called her mother "saying that she was on the Strip, and she needed money."

However, her family has since lost contact with her again and is worried for her safety.

TROUBLED PAST

Lindsey has made headlines numerous times due to a string of legal issues.

She was arrested last February in Arkansas for alleged drug possession and forgery after being pulled over because her license plate light was out.

Upon searching her car, officers found .4 grams of meth, more than $2,000 in counterfeit money, two forged checks, and a device to print more checks.

According to court documents, she was booked in the county jail on multiple charges, including possession of methamphetamine, cocaine, or heroin, possession of a forgery device, and forgery in the first degree.

Lindsey's track record stretches back further than her current shocking arrest.

In 2013, Lindsey was arrested for DUI, driving with a blood alcohol content of .08 or higher.

She was 23 then, and her blood alcohol content was .32, four times the legal limit in California.

Lindsey was arrested under suspicion of a hit-and-run and battery on a police officer.

After the incident, the star fled to a friend's house, and when a cop arrived, she allegedly punched him in the stomach.

Lindsey was sentenced to three years of probation, 129 hours of community service, and a nine-month first-offender alcohol program.

Lindsey's mother, Tammy, left the Real Housewives of Orange County after her husband's death.

Her family has since kept a low profile, rarely posting on social media.
