Kelly Clarkson digs her boyfriend, Brandon Blackstock — but she’s not a fan of how he’s affecting her career.

The ‘Stronger’ singer says that Blackstock is giving her writers’ block. “It’s ruining my creativity!” Clarkson told Zap2It. “I’m writing all this happy s—. It’s killing me,” she lamented. “Like, I’m trying to write a tough song and I can’t. It’s coming out all butterflies and rainbows. It’s killing me!”

Clarkson is worried that her fans, who are used to her fierce breakup anthems, won’t appreciate the softer side of the starlet. “People are going to be like, ‘What the hell happened to you?’” Clarkson said. “It’s been really difficult, yeah … and awesome. An awesome problem to have.”

Clarkson’s boytoy is actually her manager’s son, and she credits her manager, Narvel Blackstock, not only with introducing her to the hunk, but also just for giving her enough time to date at all. She said was perpetually single post-’American Idol‘ in part because she was so busy.

“I went from my first few years in the business with a manager who was never there … then my next manager — I wanted somebody there — and I got, like, a pitbull,” she said. “He was highly into my writing and my music, but he wanted me to be like Madonna or Britney … I don’t ever want to be those people,” she admitted. “I want a life. I love that I’m in a relationship right now, and I have time for it,” she vented. “I never used to. People would be like, ‘Why are you single?’ And I’m like, ‘Cause it’s not in my schedule.’”

We’re glad she has time for some lovin’. If anyone deserves it, it’s Kel!
