It turns out you can buy happiness!

Looking positively beaming, Lea Michele couldn't stop grinning when she stopped by Jimmy Kimmel Live in Hollywood on Wednesday night. Maybe she's lit up like a light bulb because of that big ring on her ring finger?!

Umm what?! Is that just a random piece of jewelry on her ring finger or did the big-voiced singer get engaged to her boyfriend for hire, former Cowboys 4 Angels gigolo Matthew Paetz?

It turns out Lea’s sporting pal Jen Meyer’s baubles, but seeing as she’s wearing them on her ring fingers, we have a feeling she’s fantasized about having a diamond engagement ring on her left hand!

We gotta wonder -- If Matty does put a ring on it, how many people will he have to sleep with to get the bauble? Or do you think Lea will buy a ring herself -- just like she did Matthew?

Meanwhile on her appearance on the late night show, Lea talked to Kimmel about how she threw up when she sang "Let It Go" while filming Glee. Looks like she really let it go!
