In her interview in the "Fearless" podcast, Debra Messing recalled the time she called the police after an encounter with a stalker in New York.

"This man showed up at my doorman building and he said that I invited him and that he was spending the day with me and Roman," she disclosed. "He referenced my son and that scared me in a completely different way because there was no one-on-one interaction with this person."

Per the Will & Grace star, she began suffering from severe anxiety and dealing with panic attacks whenever she was at Times Square in Manhattan.

For the second time in three weeks in 2023, the authorities arrested Drew Barrymore's stalker — identified as Chad Michael Busto — after he reportedly entered a dressing room at Brooklyn Navy Yard. At that time, he demanded to see Emma Watson because he wanted to "marry and speak and take a photo" with her.

For six years, Gwyneth Paltrow received unsolicited letters and gifts from her stalker, Dante Soiu. The suspect was found guilty as he was previously admitted to a mental institution.

In 2013, an obsessed stalker of Jennifer Lopez was able to live in her property's pool for six days without being noticed and post pictures from the area online under the pseudonym David A Lopez while claiming he was married to the Hustlers star.

On December 8, 1980, the saddening news about John Lennon's murder rocked the music industry.

The Beatles' obsessed fan, Mark David Chapman, reportedly flew to New York City from Honolulu, Hawaii, nearly two months before the killing. After planning the murder, he waited for Lennon outside his apartment building and shot him at a close range.

Lennon also sustained gunshot wounds in his left shoulder.

In 2019, two Justin Bieber stalkers were arrested for getting near the Ghost singer and his wife's property. One of them was a woman who claimed to the police that she lived in the house, but the authorities arrested and apprehended her.

Another instance involved the uncle-and-nephew duo, Mark Staake and Tanner Ruane, who reportedly received orders from convicted murderer and rapist Dana Martin.

"It isn't just so people will know who I am. It's because he changed, and that made me angry," Martin told Kevin Gray in an interview.

The obsessed fan added, "If I was free, here's what I'd want to do — put Bieber in a cage, rape him repeatedly, and put it on YouTube."
