Sheryl Crow's going to write another sad love song...

Sheryl Crow and Lance Armstrong have broken up! This is really sad news.

They were an adorable couple - one of those couples that look like brother/sister. And they were only engaged for five months. I still remember how excited she was when she declared publicly, "I want to have his babies!" So what went wrong?

I'm guessing that she wanted a baby right away (she's 43 and doesn't have a lot of time unfortunately) and he didn't - he's 34 years old and already has three kids from his ex-wife.

A couple of months ago she was quoted as saying she wasn't ready to have his babies. Hmm. I should've known then that something was wrong.

But on the plus side, I bet she'll use this experience to write another great sad, love song.

Good luck to Sheryl!
