Rosie O'Donnell Puts Her Incredible Weight Loss Transformation On Display At 'Burlesque' Premiere

Rosie O'Donnell turned heads when she arrived at the red carpet for the premiere of "Burlesque: The Musical" last night in London.

The famous comedian, who has since relocated to Ireland with her child, Clay, has been on a dramatic weight loss journey, which has been linked to Mounjaro.

The outing comes after the vocal Donald Trump critic dismissed threats from the president that he'll revoke her citizenship rights on the ground that she's "a threat to humanity."

Rosie O'Donnell stunned fans as she showed off her dramatic weight loss at the "Burlesque: The Musical" premiere in London on Tuesday, July 22.

The 63-year-old TV personality was dressed in a gray blazer and black pants, both with graffiti-style, New York-inspired artwork, for the event.

On the front of her jacket, O'Donnell had the city name repeated all over it and also had a red apple featured across the chest.

The pants also featured similar designs, incorporating stars and other drawings. She completed the look with black boots, a black tee, and her signature glasses.

O'Donnell's new slimmed-down look comes after she took to social media to confess her feelings about her weight loss.

"I can't believe this is me now," she captioned the photo, and also added the hashtags: "#mounjaro," "#weightloss," and "#bodydismorphia."

O'Donnell's weight loss has been partly linked to mounjaro, a famous diabetes drug that can help people lose weight and has been widely used by celebrities.

Back in March, she shared a TikTok update with fans where she teased that her drop in the scale could be linked to the famous drug.

"I've lost more weight. I am on Mounjaro for my diabetes, and one of the side effects is you lose weight," she said, per People. "But it's also because I had a chef for over two years in Los Angeles, and I don't have a chef now. It's me cooking for Clay and me."

The former "The View" host also spoke on how she felt about the change after struggling with her weight for years, sharing that she went shopping in Dublin to get new clothes that "fit better" following her weight loss.

"I'm one of those people who always had a weight issue, and now that I'm a size large — instead of an XL or a XXL — I find it shocking," she said. "I really do. I find it completely shocking."

O'Donnell relocated to Ireland earlier this year and is "in the process" of getting her Irish citizenship as she has Irish grandparents.

She explained that the decision was "the best for myself and my 12-year-old child" and would only consider coming back "when it is safe for all citizens to have equal rights there in America."

The comedian has been a known critic of President Donald Trump, who recently threatened to revoke her citizenship on the grounds that she's a "threat to humanity," per The Guardian.

Trump posted on Truth Social: "Because of the fact that Rosie O'Donnell is not in the best interests of our Great Country, I am giving serious consideration to taking away her citizenship. She is a Threat to Humanity, and should remain in the wonderful Country of Ireland, if they want her."

However, O'Donnell only took the threat with a pinch of salt, saying she was the latest in a long list of artists, activists, and celebrities to be threatened by the president.

"So, I didn't take it personally, but I will tell you the way that he is has emboldened people like him," O'Donnell told RTÉ Radio's "Sunday with Miriam show."

In a social media post hours after Trump's threat, she slammed the president and dared him to "go ahead and try," adding that he's "everything that is wrong" with the country.

"You are everything that is wrong with America," O'Donnell shared on Instagram, hours after Trump's threat.

O'Donnell added, "You want to revoke my citizenship? Go ahead and try, King Joffrey, with a tangerine spray tan. I'm not yours to silence. I never was."

O'Donnell and Trump have constantly taken shots at each other since their public feud began about 2 decades ago.

She first called him out in a 2006 episode of "The View" for being the "moral authority" surrounding the controversy around Tara Conner, who was that year's winner of Miss USA and was accused of underage drinking and using drugs.

"He annoys me on a multitude of levels. [He] left the first wife, had an affair, left the second wife, had an affair, had kids both times, but he's the moral compass for 20-year-olds in America," she said. "Donald, sit and spin, my friend. I don't enjoy him."

According to reports,  Trump responded at the time, calling her a "woman out of control," and has since gone on to slam her in several social media posts since then.
