Lady Gaga dragged out by Oprah

Lady Gaga had to be dragged out of her dressing room by Oprah Winfrey after suffering from stage fright.

The 'Telephone’ singer hid backstage prior to her performance at the Costume Institute Gala at the Metropolitan Museum of Art on Monday (03.05.10) – which was attended by an exclusive crowd of 700, including Anne Hathaway, Taylor Swift and Jennifer Lopez – but the talk show host helped her overcome her nerves.

A source told the New York Post newspaper: "She literally wouldn't come out. Friends tried, Warner Music executive Lyor Cohen tried, no dice. Eventually, Vito Schnabel came over and got artist Terence Koh on the phone to talk to her, which helped. Koh and Oprah were the ones who finally coaxed her out."

However, the eccentric performer was told she could only perform at US Vogue editor Anna Wintour’s annual fete on the premise she was polite and didn’t swear on stage.

She quipped to the crowd in New York City: "I'll never forget when Anna Wintour called me to play at this event, she called me and said, 'I would like you to play at the Met gala, but I just want to make sure, because I've seen you perform before, that you won't be swearing during the performance.' So Anna, I will do my f**king best!"

The 'Just Dance’ hitmaker’s performance seemingly got the guests in the mood for a singsong, as a number of A-list stars belted out tracks at the exclusive after party at the Mark Hotel.

A source added: "Pharrell Williams first jumped in and started singing 'Beautiful,' and then Sean Combs jumped up and started rapping to 'All About the Benjamins.' He even grabbed Anna Wintour into the deejay booth. Finally, Usher and Justin Timberlake joined in.

Jennifer Lopez loves a treat

Jennifer Lopez refuses to deny herself certain foods.

The singer-and-actress – famed for her perfectly curvy figure – likes to keep her diet varied and will indulge in the occasional treat but knows she can’t do it all the time if she wants to maintain her enviable body.

She said: 'Just like anybody I try to watch what I eat - there's no big science to it, which is what sucks.

'One of the good tricks is to have a goal - for me it may be getting in shape for a video shoot. The other is portion control. I love to eat everything and you pretty much can - a little piece of something fattening is not going to kill you. It's when you eat the whole box that it's going to kill you.'

Jennifer – who has two-year-old twins, Max and Emme, with husband Marc Anthony – also says she’s never felt pressure to be a size zero and has always been confident about her sexy curves.

She said: 'I was always very comfortable with who I was. I've never looked at myself in a negative way.'

When Jennifer first became a worldwide star, a lot of attention was given to her shapely behind but she insists she never paid too much attention to the stories, even when it was rumoured she had insured it for $1 million.

The 'Back-up Plan’ beauty added to Marie Claire magazine: 'I thought that story was funny. In fact, we traced that story, and that was a rumour that started in London.

'But I was honestly at that time was in such a work fog I didn't even notice. Now that I've had time to sit I appreciate and love everything in a different way, and I think that's because of the kids too. I just think of life in a different way: back then it was just about the grind.'

Rihanna’s boyfriend loves her sense of fun

Los Angeles Dodgers baseball star Matt Kemp has finally opened up about his relationship with the singer – who he was first romantically linked to in January – admitting he has never been happier.

When asked if they are a couple, he said: 'Yeah! That’s my girl.

"She's just a fun person. I love to be around her. She's definitely a great person in my life, and I'm happy I'm with her.'

Rihanna is currently on the European leg of her 'Last Girl on Earth' tour and the sportsman can’t wait to be reunited with her when she returns to the US.

He added to Us Weekly magazine: "She's definitely not gonna be here for a little while. Hopefully when she gets back she'll be at a couple more games."

The 22-year-old star recently revealed she and Matt, 25, rely on the internet to keep their romance alive when they are apart.

Rihanna – who is getting ready to bring her tour to the UK - said: "I'm really happy right now. I was hoping Matt would be able to come to London but he's working. And I'm touring and shooting videos for my next single so it's going to be seven weeks before I see him again.

"We have to make do with Skype and phone, but I miss him. I can't wait to see him again. It'll probably be when I get back to America that we can hook up properly."
