Rihanna No Time for Chris Brown?

It looks like it's all work, work, work for Rihanna this year.

The 25-year-old songstress just jetted to London yesterday to promote her River Island collection, before she kick offs of her Diamonds world tour on March 8 in Buffalo, New York.

But before heading to the UK, Rihanna was reportedly spotted spending time with her girl friends--not with Chris Brown--over the weekend, as they partied at Playhouse in Los Angeles.

Does this mean she has no time for Brown?

Well, it looks like the on-and-off couple is not letting distance pull them apart, with a source claiming that Brown would probably visit the love of his life on tour.

"If he wants to [join her] he's welcome," a source close to the lovebirds told Hollywood Life. "And more than likely, he will. You know Rihanna gets bored quickly when Chris ain't around her," the source added.

With this unpredictable pair, it's no surprise if Brown would show up during her tour, just like what RiRi did for him in 2012 when she visited his Carpe Diem tour.

The couple seems to be heading to a serious direction, with Rihanna recently admitting that she would like to have a baby with Brown.

"I will probably have a kid," she said in an interview with Elle U.K. when asked where she sees herself in five years.

Brown was quick to make a comment on the interview, saying that he feels the same way and he would probably have a baby with her, but all in due time.
