Rihanna planning to marry lover Matt Kemp

London: Rihanna is apparently planning to tie the knot with lover Matt Kemp.

The 22-year-old star has moved on from her awful relationship with R&B thug Chris Brown.

Her plans for commitment have been inspired by pal Katy Perry`s whirlwind romance with Brit comic Russell Brand.

"Rihanna adores Matt. She can`t imagine life without him," News of the World quoted a source as saying.

"Ri`s really involved with the wedding because she`s one of Katy`s best friends.

"She wants that same sort of happiness. They want a formal engagement next year and won`t take long to get married," the source added.
