Harry Styles and Zoë Kravitz’s alleged relationship is not just a fling, says an insider.

The couple, who was spotted strolling on the streets of California this week, are serious in their romance.

A Hollywood insider tells Page Six: “I feel like they’ve gone from 0-60.”

“It’s so hard to date as a celebrity … Harry wouldn’t have gone public with Zoë if it wasn’t anything,” said the source. “(But) it’s very new and fresh and they’re just having fun.”

The source added: “Harry doesn’t label this stuff.”

Meanwhile, insiders told RadarOnline about Kravitz: “She’s bold, self-assured and has this undeniable pull. People close to him believe she might be the only one exciting and captivating enough to get him to leave his playboy image behind.”

“He’s showing more effort with her than he ever has before, and that speaks volumes,” they added.

Princess Diana’s hairdresser is standing up for Kate Middleton after her latest hair makeover.

The Princess of Wales, who was spotted all blonde at the Natural History Museum reopening this month, gets saved from nasty public comments.

Former hairdresser Sam McKnight, 70, posted on Instagram saying he was “shocked, horrified, dismayed and disgusted by all the nasty comments”

She added: “A woman’s hair is very personal to her. It’s armor, defence, confidence and so much more.”

The professional continued: “I cannot believe how evil and lacking in any kind of empathy are the comments, the majority made apparently by other women, attacking a vulnerable other young woman, who has no choice, by dint of who she married and the role she took on, to bravely face the public.

“I’m sure she would rather be away from the public arena. She has brilliantly and quietly, unselfishly represented our country, the soft power we still have as a nation,” he noted.

Lizzo has an issue with the current state of the music industry, which she addresses in a recent social media post.

Taking to TikTok, the Grammy winner claims that the industry is currently in a state of “complete chaos,” voicing her opposition to the “algorithmic model” in the music industry.

She continues her rant that musicians were previously “servicing songs out to certain channels and radio stations”, adding, “an increasingly congested internet space” meant there’s no clear channel out for people to put their music out and serve the masses.” 

Despite having a strong following on TikTok, Lizzo shares that she still struggles to get the views, which she attributes to the solution: artists “have to serve your people.” 

She suggests they should make a private fan page and “have a dialogue with people that actually give a ****…” 

In other news, Lizzo reflects on her weight loss journey in an interview with Women’s Health U.K.

“I like how I look now. I still think I’m big. I’m still wearing plus-size clothing. I have the same rolls. I got the same belly, the same thighs – I think I’m just a smaller version,” she shares.

The Pink hitmaker continues, “Body positivity has nothing to do with staying the same. Body positivity is the radical act of daring to exist loudly and proudly in a society that told you shouldn’t exist.”‘

Lizzo, meanwhile, released her third mixtape, My Face Hurts from Smiling, earlier this summer.
