Amanda Bynes’ erratic behavior continues as she admitted to Us Weekly that she wants to lose 20 pounds.

The celebrity-gossip magazine featured the former child star Friday in its “25 Things You Don't Know About Me” series, where her drastic weight-loss goal is No. 15 on her list.

“I moved to New York City, and I love it! I lost 4 pounds since I moved. I'm 121 pounds -- my goal is 100 pounds,” Bynes told Us Weekly.

She also mentioned she supposedly gains weight quickly and needs to work out constantly.

Standing 5 feet 8 inches tall, Bynes is already quite slender. The National Heart, Lung, and Blood Institute's body-mass-index calculator indicates a woman of her height should ideally weigh between 122 and 164 pounds.

Bynes has recemtly been sharing her exercise routine on Twitter.

On Feb. 7, she said, “I just got done working out,” with an icon of an arm making a muscle.

On Feb. 8, she tweeted that she was taking gymnastics classes.

And on Thursday, she wrote she was on her way to a stripper class. The Daily Mail noted many women practice pole dancing as an unorthodox form of exercise, one becoming increasingly popular.

Months ago, the aspiring fashion designer alluded to her desire to lose weight, sharing on Instagram a photograph of her legs in a pair of ripped jeans with the caption: “Losing weight is hard to do! I love jeans with sexy holes, mine are from Current Elliot :D.”

However, the eccentric actress still seems to have her indulgences. On her Us Weekly list, Bynes also admitted her love for Diet Coke, eggplant parmesan, and macaroons.
