Blink and you'll miss a tweet. Scroll too fast and that all important selfie will never dazzle your eyes. Don't panic, as we have this weekly guide on what your favourite celebrities have been up to on social media. Here is what has been happening this week -

Could this be the most beautiful selfie in the world?

You have to hand it to Gavin and Stacey star James Corden, he never fails to make us laugh. The Brits presenter took the opportunity to take a selfie with Prince, and he posted it straight on Twitter. We think this could possibly be the best selfie ever! Like ever!

Celebs and the City

This has to be the most celeb-tastic picture we have seen Kim Kardashian post to date! Kimmy took the picture  backstage at Jimmy Fallon's show in the US. She is pictured with - here goes - Mike Tyson, Sarah Jessica Parker, Tracy Morgan, Joan Rivers, Lady Gag and Lindsay Lohan. Phew! Now that is a dream celebrity dinner guest list, if ever we saw one.

Ice Ice Quinn

The going seems to be getting tough for Dancing on Ice star Ray Quinn as he reaches the final stages of the competition. Ray, who won series four, ironically rested his foot in a bucket of ice - hasn't he had enough already? - in this picture he posted on Twitter with the word, "ouch". We can only imagine the pain he is in...Dancing on Ice is one tough competition. But Ray still manages to make it look so easy.

Eric's got the X-Factor

Simon Cowell showed off his tender side on Twitter this week by posting a picture of his newborn son Eric. The tot, named after Cowell's late father, was welcomed to the world last Saturday. We have to say this picture is just adorable. Simon tweeted alongside the picture, "I never know how much love and pride I would feel." Our hearts have kind of melted. Congratulations to Simon and Eric's mummy Lauren Silverman.

When Oprah met Tinie...

A delighted Tinie Tempah spoke of his delight at meeting Oprah Winfrey at the Bafta's this week - and who can blame him? She is a legend! The star posted a picture on Instagram, saying, "Another one ticked off the bucket list! Truly an inspiration in every sense of the word. Need I say more."

Baby on the way for Mr Selfridge star...

A very pregnant Katherine Kelly showed off her baby bump on Twitter this week with the comment, "Still cooking!" The actress, who plays Lady Mae on hit ITV show Mr Selfridge, announced her pregnancy last September...a month after she married her husband Ryan Clark in Las Vegas. She looks fantastic!

Kelly is the one and only...

Gorgeous Kelly Brook posted this picture of herself with 90s heartthrobe Chesney Hawkes on Instagram. The singer famed for the hit, The One and Only clearly captured the model's heart. She said: "Yes tonight I met Chesney Hawkes and I asked for a picture #iamgeek." We would have done the same thing Kelly, you go girl!

When in Paris...

A loved-up Tamara Ecclestone posted a picture of herself and partner Jay Rutland at the love lock bridge in Paris. How romantic! Tamara is expecting her first child which is due in November.

Nicole gets 'in the zone' with Britney

Possibly the dream of every Britney Spears fan is to have a moment on stage with the superstar. And lucky Nicole Ritchie had that dream realised when she went to see Britney's show in Las Vegas. She posted some of the pictures from the moment on Instagram, and we are so envious! We want to be on that stage with Britney too!

New look for Katie

Katie Price aka Jordan took to Twitter to show off her short hair this week. She tweeted, "Short hair we go lol."
