A video clip showing Paris Jackson singing to boyfriend Chester Castellaw reportedly raised red flags on the state of her mental health, as marriage rumors are hounding the couple.

The clip in question showed Michael Jackson's daughter grabbing her boyfriend's face as she drew him to her and sang.

"This is my baby, if you flirt with him, touch him, talk to him, think about him, or even look at him, I will slit your throat!"

Radar Online talked to an alleged close friend of Chester Castella who said that Paris Jackson is acting "crazy."

"Everyone thought she was back on track," the alleged source said exclusively, "but now it looks like she's on the verge of a meltdown."

Radar also claimed that a psychologist was shown the video and concluded that the way Paris Jackson-who slashed her wrists and tried to overdose on pills in 2013-was acting is not healthy.

The meltdown was supposedly caused by Paris Jackson not seeing mother Debbie Row in over a year and that has affected the teenager's fragile psyche.

The tabloid also claimed that Paris Jackson is pressuring boyfriend Chester Castellaw into marrying her when she turns 18 next year.

"I'm afraid if she tries to push Chester into marriage, he'll dump her, then all hell will break loose," a friend added.

Meanwhile, Paris Jackson has denied that the Instagram account with her adopting boyfriend Chester Castellaw's last name, which sparked marriage rumors, is a fake.

"In a video posted to her bf Chester Castellaw's alleged page, Paris asks fans to help her get the impostor account -- which has racked up more than 200k followers -- removed. She claims she does not have a public profile," TMZ said

"It's interesting ... the video doesn't address marriage rumors but a source close to Paris says the two aren't married," it added.
