The 'Perfume' hitmaker is reportedly embracing the ancient relaxation technique after being encouraged to chill out more by her boyfriend Charlie Ebersol.
A source said: ''Britney seems more at peace since she started meditating.
''Charlie is a meditation enthusiast. He's always been interested in self-help and a clean lifestyle, so he's a really good influence on Britney.''
The 33-year-old beauty - who has sons Sean, nine, and Jayden, eight, with ex-husband Kevin Federline - has already started practicing alone on a daily basis before her concerts in Las Vegas.
The insider added to Life & Style magazine: ''She has a mantra and she meditates for 15 minutes before performances to centre herself and calm her nerves.''
Charlie - whose parents are NBC executive Dick Ebersol and actress Susan Saint James - recently admitted he and Britney are homebodies.
The 32-year-old TV and film producer explained: ''The thing that I learned from my parents was no matter how busy you are, home base is the single most important thing. As long as you're centering back to home base and that's the strongest magnet in your life, that everything else is OK.''
