Diaz hasn’t been involved in a serious relationship since splitting from pop heartthrob Justin Timberlake last year.

She said: “It’s been nice not having a boyfriend for the past year. In fact, it’s the first time I haven’t had one in 10 years and I’m enjoying what I’m getting out of this moment.

“I could be in a relationship if I wanted to be but I haven’t finished doing what I’m doing. But when I’m in a relationship I’m very loyal and committed. I give a lot.”

Cameron - who dated Justin for almost four years - insists she gets lots of romantic offers but believes some men are intimidated by her because she is a “lot of woman”.

The 35-year-old actress added in an interview with GQ magazine: “I do get asked out. It’s fun. But I’m a lot of woman - in a lot of ways.

“And I understand that can be intimidating.”

Britney Spears got the thumbs up from former duet partner Madonna on Thursday.

In an interview on New York’s Z100, Madonna told host JJ that she is a fan of Spears’ “Blackout.”

“I actually love Britney Spears’ new album. I listen to that a lot,” Madonna said.

 In fact, she does more than just listen. “I usually work out to her record,” Madonna said. “I do a combination of Pilates and dance aerobics.”

Madonna also got candid about Britney’s ex, Justin Timberlake, who contributed to her new album “Hard Candy,” which comes out April 29.

Earlier this month it was revealed that Madonna had given Timberlake a Vitamin B shot. It wasn’t so she could see his bottom, as Z100’s JJ suggested.

“I mean, I’ve seen enough butt so that’s OK,” she sighed. “The reason I gave him a B12 shot is cause we only had a certain amount of days in the studio and I didn’t want him using that as a lame a– excuse not to come to work, OK? It’s got nothing to do with butt, I promise you. Listen, I don’t need to give him a shot to see his butt.”

Madonna also revealed that she has no plans to sing some of her classic songs ever again.

“I’m not sure I can sing ‘Holiday’ or ‘Like A Virgin’ ever again. I just can’t,” she said. “Unless somebody paid me like $30 million or something.”

Float like a butterfly, sing like a bee… here’s Madonna proving she’s still The Greatest.

As the Material Girl approaches her 50th birthday this September she shows there’s still plenty of fight left in her.

Far from being on the ropes, she vowed to “kick all of their asses” as she promoted her new single with Justin Timberlake - who is young enough to be her son.

Wearing five-inch heels and boxing gloves, she said middle age was not going to slow her down.

“You’ve got a lot more experience and you tend to not make the same mistakes,” she tells Interview magazine. “It’s great to feel experienced. But I also work with people who are half my age, so I feel like I have to work even harder to keep up with everybody - but the fact of the matter is I can kick all of their asses.”

In a bizarre move, Madge has decided to release her single tomorrow as the theme tune to a shampoo ad, rather than in record shops or online.

The record - Four Minutes To Save The World - is about fighting poverty and disease.

And as boxer Muhammad Ali once said: “A man who views the world the same at 50 as he did at 20 has wasted 30 years of his life.”

Well that’s certainly not something anyone could ever accuse Madonna of…

Justin Timberlake is looking to bring viewers back to NBC.

The pop star is teaming with Reveille, the production company behind Ugly Betty and The Office, to bring the hit Peruvian comedy My Problem with Women to the Peacock net, NBC confirmed Friday.

Timberlake will serve as an executive producer on the project, which is based on Peru’s Mi Problema con las Mujeres, a show that launched in July and has since been sold in 20 countries.

“I am very excited to be collaborating with Reveille to bring this hugely successful format to NBC,” the singer said in a statement.

In other Timberlake news, Mr. SexyBack will be inducting none other than Madonna into the Rock and Roll Hall of Fame on Monday. The duo recently collaborated on the Queen of Pop’s upcoming album, Hard Candy, which is due out on Apr. 28.

Up ahead, Timberlake stars in the comedy The Love Guru, opposite Mike Myers and Jessica Alba. The film is slated for a June 20 release.

He is currently filming the drama The Open Road, opposite Jeff Bridges and Kate Mara.
