According to a source close to the Brown family, "Raiven met Bear when she came with her mom Kassy to do the photos for Noah's romantic wedding last summer.
"She was welcomed into the Brown family with open arms. Bear has also met her family and they are so happy together!"
The lovebirds didn't immediately go public with their relationship -- but have saved it for reality TV.
The upcoming season of Discovery's hit show premieres on August 4 and RadarOnline.com has discovered that Bear and Raiven's relationship will unfold on television.
"I am so happy and feel so complete with Bear in my life and I know that we can get through anything," the brunette beauty said.

In this photo posted to Raiven's Instagram, she wrote in the caption, "If I could have two more sisters sure would be you two!"
Although Raiven now lives in Washington, which is where Bear's famous family shoots their hit TV show, she is originally from Colorado.
SO HAPPY TOGETHER
"Bear and Raiven are a perfect match and they are very happy," the source told RadarOnline.com. "He is the man of her dreams and although some think their moving too fast, they do not see it that way at all."
So is there another Brown wedding in the future? It is likely, the source said. "Of course Raiven wants to one day be married one day and she also wants kids. What girl doesn't?"
