My girlfriend just compared me to Fiona, ogre version- should I be offended?

I was in the middle of doing my nightly skin care routine and putting on my sleep clothes in the mirror when she came over and was telling me how beautiful I looked until she said “this is a hot take and may come across weird and I promise it’s not, but you’re like Fiona from Shrek in ogre form and she’s a baddie.” I did not know how to truly respond to this. For context: she is genuinely a sweet and kind human being and I know she finds me sexy and beautiful, I’m just not sure how to take being compared to specifically Fiona, ogre version 💀💀💀. It’s baffling but funny to me but I’m not sure if I should be offended? Thoughts?

If it helps any, I’m not green.
