A Miley Cyrus-obsessed fan was arrested after he threatened her and allegedly said he wants to get her pregnant.

According to TMZ, 42-year-old David Rumsey was detained by the "Slide Away" singer's security at her iHeartRadio show in Las Vegas on Saturday (September 21). He was later arrested and booked into Clark County Jail on a "felony charge of making threats" following a series of bizarre messages posted to his Twitter account.

Cyrus' team was on high alert after seeing his Twitter feed, which included tweets like: "here waiting for your concert. I hope we can meet up before the concert. I'll get a room where ever you want" and "sorry for hurting you before. I blame trump and hope you can see past what happened."

"I know after we are together we can party it up with 2pac, biggie, Prince, Michael Jackson and all those we lost. So any party you might have planned will be more of a pre-party," he wrote in another disturbing message.

Considering all four people he mentioned are dead, this is definitely not okay...

Rumsey also reportedly told her team, "It's my life's mission to impregnate Miley."

The scary fan encounter comes just a couple of days after Cyrus reportedly broke up with Kaitlynn Carter. The two had a whirlwind romance following the pop star's split from husband Liam Hemsworth.

"They’ve been friends forever and were there for each other when they were both getting separated," a source told to People. "But they’re just not in a romantic relationship anymore."
