Britney Spears is trying hard to lose weight after paparazzi published what she felt were unflattering photos of her in a bikini.

“I’ve been working really hard to loose [sic] weight .... and for me 3 pounds is like 7 pounds it’s a lot,” Spears, 37, captioned an Instagram video of her latest workout on Monday. “I don’t like doing too much cardio. My body has muscle memory, cus [sic] I use it be gymnast and I can bulk up .... so I like isolated movement.”

“The key to my workout is repetition, but that gets boring so I have a booklet I’ve made with all my favorite exercises. I usually wear headphones .... music takes me away," the "Baby One More Time" singer added. "I know I don’t look perfect here, but I’m working on it. Hopefully one day I can give my boyfriend’s abs a run for their money !!!!”

Boyfriend Sam Asghari commented, "Perfect as it can be! Lioness always inspiring the world!"

Earlier this month, Spears claimed that the MEGA Agency doctored photos of her vacationing with Asghari in Miami.

“A lot of fans, in our world today, they always are subject to really criticize people and say that the pictures and videos that they’re posting are either not on time or they’re fake," Spears said in an Instagram video. "But no one ever really asks, ‘Are the paparazzi pictures fake, and do the paparazzi people do stuff to the pictures, and is the news really real?’ It’s a conspiracy theory that I’m actually interested in.”

MEGA vehemently denied Spears' claims in a statement to Page Six, noting, “We think Britney looks great and it’s ludicrous to suggest the photos or video were altered in any way. They were not. We shot thousands of photos of her over the weekend and are very happy to let her see the original files if she so wishes. It was good to see her happy and having fun and we wish her well.”
