This week singer and actress Selena Gomez celebrated her 21st birthday and the stars came out to wish her a happy arrival at the legal drinking age in the US. Firstly Gomez did a coming of age interview with Ryan Seacrest in which the pair drank Mimosas, played Connect Four and chatted about Selena's relationship with her ex Justin Bieber. Next came a tweet from the brunette's best friend Taylor Swift who missed out on her pal's birthday because she's currently performing on her Red Tour on the other side of America. Swift tweeted a photo of the two girls posing as mermaids along with the caption: 'Happy 21st birthday to my friend, and the closest thing I've ever had to a sister.'
Selena spent her actual birthday at Bagatelle restaurant in West Hollywood wearing a pair of white hotpants and goofing around with a large group of friends. Last weekend the star joined the likes of Lily Collins, Glee's Chord Overstreet and Jesse Metcalfe at Julianne Hough's 25th birthday party, which had a Great Gatsby flapper theme. The A-list guests shared selfies of their elaborate costumes, including masks, hats and glamorous 1920s makeup.
Meanwhile Tom Cruise and Nicole Kidman's son Connor has joined his sister Bella in London in an effort to explore the city. Bella has been in the British capital for the last three months and told Grazia at a recent party, "I absolutely love it in London, the shopping here is really cool; I love all the vintage stores, it's really great not to be recognised." Perhaps going incognito is what spurred the siblings on to join the Barclays Cycle Hire scheme and do a spot of sightseeing. Connor added some photos of their day out on Instagram and explained, "Exploring the hitherto unknown world of London England #MakesNoSense." If only Tom had been in town too - we'd love to see him on a Boris Bike.
And finally, both Alexa Chung and Heidi Klum have been sharing snaps of themselves catching some shuteye. While supermodel Heidi settled down for sleep on a recent flight Alexa attempted a power nap on the floor. Zzzzz.
