Rihanna is preparing for her 'Diamonds' world tour with the help of her mother and boyfriend Chris Brown.

Chris has been in constant contact with the 25-year-old 'We Found Love' singer while Rihanna has also turned to her mother Monica as she prepares to hit the road.

A source told HollywoodLife: "Chris wished her a good show a few nights ago.
"She been talking to her mom, you know, getting her head right."

Meanwhile, Rihanna can't wait to get out on tour and is taking it easy in rehearsals so she saves her energy for her fans.

The insider added: "She's good, excited to kick off this [tour] and do it big. She's already hyped up and doing some light rehearsals but other than that, she's taking it easy. Saving all the energy for the show."

Although Chris is still on probation for beating Rihanna up in 2009, she recently spoke of her love for the 23-year-old rapper and admitted she couldn't continue to bury her feelings for him, even after the assault.

She said: "I wanted him to know what it felt like to lose me, to feel the consequences of that. So when that s**t [love] came back, it hit me like a ton of bricks.

"Like, God, you've got to be kidding me right now. But I got real with myself, and I just couldn't bury the way I felt."
