Amanda Bynes has launched a vicious attack on celebrity blogger Perez Hilton, demanding he "stop living" and kill himself after he posted an article suggesting the troubled actress had been spotted at an indoor trampoline park.

The 27 year old actress has been lashing out at gossip about her erratic behaviour and legal issues in recent months, taking to her page to blast reporters, bloggers and fellow celebrities for raising concerns about her mental health.

Perez Hilton, a former friend, has had the worst of the backlash after he urged the Hairspray star's parents to step in and seek out help for the embattled star.

And now Bynes has taken aim at Hilton again after he shared an eyewitness' blurry picture of a brunette, purported to be Bynes, having fun at Sky Zone trampoline centre in Buffalo, New York.

She fumed, "That's Not Me! I'm so sick of fake fans such as Perez Hilton! Send the picture to me privately first to confirm that it's me! I've never been to SkyZone! That looks nothing like me! I don't own a brown wig!"

The Hairspray star then continued her tirade by tearing apart the gay blogger for his looks and his lifestyle.

She wrote, "@perezhilton no one wants to s**k your d**k! Stop living! Kill yourself! I look sooooo much better than the girl you hired to look like an awful cheeky version of me! So I'd say F**k You but no one wants to! I just say keep living in your s**tty existence leaching (sic) off of stars who you look, sound, and act nothing like (sic)!"

Hilton has yet to speak out about Bynes' shocking comments, but took a screen grab of her hateful words and shared it with his Twitter followers on Thursday morning (30May13).

Meanwhile, bosses at the Sky Zone centre have confirmed that the actress did pay them a visit on Wednesday (29May13).

One staff member tells In Touch magazine, "She was at the Sky Zone Buffalo location yesterday at 7pm. She was there for about an hour. She was jumping on the trampoline and she was pleasant to the staff.

"I know she says she wasn't there but we can confirm she was. She was jumping on the trampoline and that’s all she did."
