The `Diamonds` singer - who recently reconciled with 23-year-old Chris who is still on probation for beating her in 2009 - stepped out to attend the launch of his new desktop channel `Qubeey` in Los Angeles last night where they were spotted hugging and kissing.
A source told Hollywoodlife.com: "[Rihanna] had fun last night being with Chris. She loves him and anything she can do to support him she will. She wants to be by his side and show up for him and last night she did." The Qubeey channel is Chris`s new customised website that will enable his fans - which he calls "Team Breezy" - to get more exclusive access to the singer`s life through photos, videos and personalised messages.
The couple were spotted kissing and sharing drinks and a cigarette at the bash at Playhouse nightclub in Beverly Hills before leaving separately.
The source said: "Chris was real soothing - he made [Rihanna] feellike a princess just by the little things he was doing. He opened doors, pulled out her chair, you know, being charming Chris. He was being a gentleman and it was cute. They had a few kisses and some drinks, but the night wasn`t about them as a couple, it was about Chris and his channel - and she wanted to be there for him."
But friends close to the couple insist they are taking their relationship slowly despite being happy to be seen together.
A friend said: "They`re easing into everything, but so far so good. Rihanna knows what she`s doing. This is her moment with Chris. Only thing is - it`s going to be a long a** moment. She`s so good with him. She`s so happy."
