Amanda Bynes conceals Ozempic weight loss in flowing outfit as she runs errands with boyfriend Zachary Khan

Amanda Bynes enjoyed a leisurely Sunday with her boyfriend Zachary Khan.  

The Nickelodeon legend, 39, was spotted out in Los Angeles with her love, stopping by Lady M Cake Boutique and getting their car washed.

While Khan tucked into a hearty burrito, Bynes sat across from him with her vape in hand and what appeared to be a snack and beverage sitting between them.

Bynes, who is now down 28 pounds after going on Ozempic, was definitely dressed to impress for the laid-back occasion, but in a look that concealed her recent weight loss. 

Blonde hair slicked over her head, Bynes sported a flowing graphic print T-shirt and baggy star adorned trousers. 

The former child star has lost 28lb thanks to a new weight-loss drug after she hit 180lb during her heaviest.

Functional nutritionist Monica Partier previously told Daily Mail the movie star looks to be losing weight weekly, which has made her overall weight loss even more dramatic.

'She appears about five pounds thinner than she did last month, which means her weight loss drugs are really working for her, so I would put her overall annual weight loss at 35lb and guess she is a size 4,' Partier told the Daily Mail.

'Not all weight loss medications work that well, it really depends on the drug and the person - sometimes it is not a match, sometimes it is,' she added.

'Clearly, the drugs Amanda is using are a good fit. She also looks healthy with glowing skin, which suggests she is eating right. And because there is no extra skin on her arms or around her neck, she is likely working out often to tighten up as she loses weight.

'It looks like she is doing all the right things.'

If Bynes plays her cards right, she could be able to keep the weight off even if she goes off the medication.

Partier added, 'As long as she is eating high-protein, vegetable-loaded meals with little processed foods, little dairy and hardly any sugar, she should be able to stay slender once she quits the medication.

'There is a way to maintain the weight loss, she just needs to be diligent.'

That means fried foods and a lot of sugary treats are out. 'If you really want to keep your weight low, you have to stick to whole foods that are full of nutrients. But there are always good fats that can be consumed, like nuts and avocados.'

Bynes rose to fame in the early 2000s for her comedic role on the WB sitcom What I Like About You and several teen-oriented movies, including Hairspray, Big Fat Liar and Easy A.

In March 2024, Bynes shared on Instagram that she had piled on more than 20lbs after she had depression.

The Love Wrecked star said: 'I'm doing a lot better now and have learned to do opposite action when I don't feel like working out or eating clean. I weigh 162lb. right now and want to get back to 110lb.'

Last year, she announced on Instagram that she was launching an OnlyFans account.

Speaking about why she decided to join the platform - a paid internet content subscription service that is popular with pornographers, but is also used by other content creators - Bynes said: 'Disclaimer: I'm doing OnlyFans to chat with my fans through DMs. I won't be posting any sleazy content.'
