Megan Fox and Machine Gun Kelly were first linked together last month
Weeks later, a source tells PEOPLE Fox, 34, and the 30-year-old rapper, whose birth name is Colson Baker, have been spending more and more time together.
"They hang out at Megan's several times a week. She only sees him when the boys are with Brian," the source tells PEOPLE of Fox's three kids with Green: sons Noah Shannon, 7, Bodhi Ransom, 6, and Journey River, 3.
"The relationship seems too new and not serious enough for Megan to introduce him to her kids. Megan seems very happy though," the source adds.
On Monday, the two went public with their relationship when they were pictured holding hands and kissing after leaving a bar in Los Angeles. That same day, Baker tweeted lyrics from his most recent single "Bloody Valentine" that seemingly called Fox his girlfriend.

Green first revealed he and Fox had split on an episode of his podcast …With Brian Austin Green titled "Context."
The actor said their split came after Fox returned to their California home following months apart as she filmed a movie abroad with Kelly.
"She said, 'I realized when I was out of the country working alone that I feel more like myself and I liked myself better during that experience and I think that might be something worth trying for me,' " Green recalled what Fox told him during the conversation. "I was shocked and I was upset about it, but I can’t be upset at her because she didn’t ask to feel that way. It wasn’t a choice she made, that’s the way she honestly felt. We talked about it a little more and said let’s separate for a bit … and so we did."
