Britney has been gradually regaining form for weeks now, and tonight in Moscow, the blonde was back to her very best.

Looking lithe and toned in the revealing corsets she dons on stage, the 29-year-old hasn't even a hint of the paunch she sported at the start of the Femme Fatale tour. The Hold it Against Me star kicked of the European leg of the extravaganza in St Petersburg, Russia, Thursday night to a rapturous response, though it was not sold out. Undeterred, the mother-of-two has been trying to immerse herself in European culture. Before her concert in Moscow, she decided to visit the  Salvador Dali exhibition in the Pushkin Museum of Fine Arts. But with 70 million albums underneath her often rhinestone-encrusted belt, she says she doesn't need to persuade anyone to buy into the music.

She said: 'I don't really have anything to prove at this point. I just do it for fun and see what happens. I have a good group of people around me. We have the show at a certain time every night. And we just try to stay consistent on having a routine and staying fit and healthy. The show is really fun for me, it's one of the most entertaining shows that I've ever done.  There are six or seven costume changes, the dancers are just on fire and it's a lot of fun. It's a fun show.'

The singer will hit the big 30 in December, but isn't concerned about leaving her often troubled twenties behind. She told the Associated Press: 'I hear the older you get, the wiser you get and the more you know what you want. Hopefully it'll be a good year.' And she had some advice she'd give to any pop wannabes. 'I would probably say just have fun, take it slow, don’t go too fast,' she warned. 'Make sure you treasure the moments.'

After her failed marriages, Britney is now in a happy relationship with William Morris agent Jason Trawick.  'I am in a very good place, I am busy, I am doing what I love, my family is great,' she added. 'I am finding my whole click with life.' The birthday comes during the South American leg of shows, so she's planning a suitably exotic celebration. 'Hopefully me and the dancers will get together and do something really spectacular.'
