Celine Dion has advised Britney Spears to prioritise her children over her Las Vegas residency.

The 'Think Twice' singer thinks the 31-year-old 'Work B***h' hitmaker, who has two sons, Sean Preston, eight, and Jayden James, seven, with her ex-husband Kevin Federline, will need to have a good support system in place so she can balance motherhood with her upcoming concert schedule.

The 45-year-old star, who has three sons of her own, told 'ET Canada' on Tuesday (01.10.13): ''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. I think she can really do it!''

But she added: ''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.''

Celine is on her second successful residency and has been performing at Caesars Palace in Las Vegas since 2011.

Britney will perform 48 shows a year for the next two years as part of her new $15 million deal with the Planet Hollywood Hotel and is set to kick off her first performance on December 27.
