Baby Aloud

Girls Aloud star Nadine Coyle showed off her adorable little girl Anaíya on Instagram this week. We can't get over how cute this baby is! She said: "3 months, living it up. My baby."

Dem award-winning babies

They might be only three-year-old but Mariah Carey's adorable twins Monroe and Moroccan are already eyeing up the award gongs. Dem babies, as Mariah and her husband Nick Cannon affectionally call them, were pictured holding World Music Awards. Mariah took home a Pop Icon award at the prestigious ceremony in Monaco.

Could it be magic?

Britain's Got Talent's hunky illusionist Darcy Oake posted this picture on Twitter of himself with another magic man - Dynamo. He said: "@Dynamomagician absolute honor to meet you today." We are rooting for Darcy on Britain's Got Talent - he has to be the best looking contestant ever, not to forget talented, don't you agree ladies?

Liam's wish is everyone One Direction fans command...

It is expected that everytime the One Direction boys create a Twitter hashtag, the chances are their legions of fans will follow. Liam was having a rough day this week so he decided to get all his One Directioners to wear a hoodie. Hands up, who put on their hoodie?

Fashion

Pharrell Williams has been making waves wearing his outrageous Vivienne Westwood hats recently - and it looks like he has been getting more tips from a fashion icon. The singer posted this picture with Karl Lagerfeld - and simply said #legend. Maybe Karl can pursuade Pharrell to try a new trend...

Minty fresh

Former Hollyoakes star Ricky Whittle showed he has gone a little American on us since he moved stateside - by supersizing his mouthwash. Talk about fresh breath...

Looking good

We have to admit we are used to seeing celebrities looking perfect on their selfies. Hillary Duff, however, took us by surprise this week with her fantastic selfie. The singer/actress looks amazing. She is mummy to son Luca and yet she looks like a superstar - we want to know how she does it?

Cheryl's Comeback

Miss Cheryl Cole is on her way back with new music. The singer revealed that her fans can have the first listen of her new single Crazy Stupid Love which features Tinie Tempah - this week. Who is excited? We say this as we hunt a gold swimsuit - how amazing does Chezza look? The single will be out on July 20 and radio stations across the country will debut it on Monday.

Gaga's working

Little monsters - the name for Lady Gaga fans - there is no need to worry about your favourite diva - as even she admits she has been quiet of late. She posted this picture on Instagram and said: "Miss you monsters. Been writing a lot of poetry. It's so hard to write sometimes. I'm afraid of what I'll read." Cheer up Gaga...

Katy B's Got Talent

Katy B was very excited to be on Britain's Got More Talent this week. She said: "Arrived at Britain's Got More Talent studios!! Coz guess what mi darlings! I'm performing 4 songs on the show tonight!" We have to admit we love Katy B, she was fantastic at Radio 1's Big Weekend in Glasgow.
