Matt’s friend says, “Matt is very happy to be moving in with Rihanna. He knew it was only a matter of time before Ri moved him in. He wants to make her happy. He’s keeping his house, to see how things go, but the are so in love.”

And we also hear Rihanna has met Matt’s family! He reportedly introduced them when she attended an Ante Up for Autism charity fundraiser he was involved with.

“Matt was happy she came,” a source said. “It was an awesome show of support. Rihanna fit right in as if they all knew each other. It was comfortable.”

Rihanna and Matt were first romantically-linked in January, after they were spotted on vacation together in Mexico. Seems like things are moving along nicely! And it’s so like Rihanna to not talk about her relationship.
