And why not? She's in love!
Or does have other motives??
The 33-year-old star has been dating over a year, and while things are pretty solid between them, it concerns her that the 43-year-old has never been married despite having long-term relationships in the past.
He even has an 11-year-old daughter with his ex, Kate Beckinsale, but after 8 years, she was "embarrassed" when he didn't propose to her.
A source adds:
"[Rachel] is 33 now and at the top of her game – she’d love to marry and have kids. If Michael is determined to remain a bachelor, she’ll have to make a tough decision. Stay with him on his terms or move on."
Totally a tough decision, but maybe she needs to give him a little more time?
Just don't let him break your heart, Rachel!
