Lady Gaga has marked her 30th birthday in style, as she was joined by a host of her famous friends at a star-studded bash in Hollywood.
The 'Bad Romance' singer threw a typically lavish party at LA's No Name club on Sunday (27 March) night.
But they were not the only big names on the guest list, oh no.
As was Mark Ronson, who is working with Gaga on material for her upcoming fifth album - a follow-up to 2013's 'ARTPOP'.
The birthday girl herself was all smiles as she arrived at the LA nightspot hand-in-hand with fiancé Taylor Kinney.
She was wrapped up like a present in a metallic gold mini-dress with pouffy sleeves, wearing her peroxide hair up, with a rouged lip finishing off her look.
It was an early celebration for Gaga, who officially turns 30 today, and she got her birthday off to a very hungover start.
The morning after her party, she tweeted:
As well as working with Mark Ronson on her new album, she has also reunited with producer Red One, who she collaborated with on some of her biggest hits including 'Just Dance', 'Poker Face' and 'Bad Romance'.
Speaking of her new material, he teasingly told The National last year: “We took a little break from each other and now it feels like we are in a good place, both of us. She did her thing, I did my thing, and it feels like we’re back on track together... the new material feels great."
It is widely-expected that Gaga will release her as-yet-untitled fifth studio album later this year.
