Now Celine, who has a string of blockbuster Las Vegas gigs under her belt, has reached out to the troubled star to offer her some Vegas advice.

"What I wish for her, especially as a mother, is for her to find wonderful people who can help her find a balance between the artist that she is and the mother, and to try and find an emotional balance to cope with those two and be the best of both worlds," said the Think Twice singer.

Speaking to ET Canada, Celine went on to praise the celebrity, adding she was already a pro.

She said: "I think she can really do it. I don't think she needs any advice from me. She's been there, she's been on stage, she's shook it all out. She's very talented and knows exactly what to do."

Mum of twins Celine has had a mainstay show at Caesars Palace since 2011 and is now on her second successful residency in Las Vegas. Her first show, A New Day, had a five-year run that racked up 700 performances and pulled in three million people.

Britney, who released her new track Work B**** days before agreeing to the Vegas deal, could do a lot worse than take heed.
