And their relationship may be in jeopardy.
So who is this person Amanda Bynes can't stop Tweeting – and fretting – about?
The Hairspray star hasn't said and her reps aren't talking. Speculation has focused on Canadian rapper Drake after he called her "Penny Lane" in one Tweet, and she noted in a message they have something in common: "Drake is half Jewish like me ... word!"
But back in February she Tweeted, "FYI I've never met Drake! We have a mutual friend but we haven't met yet! So for some reason people think we're dating but we're not!"
Whomever it is, she appears smitten. "You're the best, which is why I'm saving you for last," she wrote before quoting love lyrics from Rihanna and Jay-Z and raiding iheartquotes.com for further inspiration.
The new flame may actually be an old one. On Valentine's Day, Bynes announced she was newly single and said she was glad she never revealed his identity. Then this week she wrote, "Things we lose have a way of coming back to us in the end, if not always in the way we expect," she hinted, quoting from Harry Potter scribe J.K. Rowling.
Whomever the man is, he was rocking Bynes's world for weeks. She writes: "It's amazing when someone knows how to love you with out being told."
Then, this Wednesday, things took a turn."I have a friend that I thought was like a sister to me," she wrote. "She's been lying to me and she has been up to no good with the man I like."
She added, "Some people make me sick."
How will it turn out? Stay tuned...
