Chris Brown has reportedly bought Rihanna a $100,000 diamond necklace.

The 'Don't Stop the Music' singer, who is widely rumored to be dating the R'n'B star and was recently seen kissing him in a KFC fast food restaurant, was thrilled to discover Chris had splashed out on a ruby and diamond necklace from jewelers Jason of Beverly Hills.

Jewelery designer Jason Arasheben revealed, "Chris went for the heart theme. He said, 'She's going to love this because she loves hearts'."

20-year-old Rihanna, full name Robyn Rihanna Fenty, was so impressed with her sparkling gift that she has ordered a diamond-encrusted cross for 19-year-old Chris from the same jewelers.

Jason added to America's OK! magazine, "Rihanna gave specific instructions about Chris' gift. She was very particular about wanting the cross to match his other jewelery."

Rihanna was first linked to Chris in February after he attended her 20th birthday. They are believed to have gotten matching star tattoos on their necks during a romantic holiday in Jamaica, where they were also spotted fondling each other in a pool.

Rihanna has previously denied she is dating Chris, insisting he is like a brother to her.

She said, "We are best friends, honestly, like brother and sister. I won't say that we're just friends - me and Chris are really best, best friends."
