The star, 43, is a sucker for peanut M&M’s and singing in the shower, and chatted with PEOPLE this week about “one last thing” …

Last indulgence
Sadly, last night. I’m staying at my best friend’s, and there’s a giant bag of peanut M&M’s. Here’s the thing: They add up over a week. I’m like, “You’ve got to hide these!”

Last song I sang
Florence + the Machine’s “Over the Love” in the shower. The water obscures all the notes you don’t hit. If you don’t sound awesome, there is something wrong with your shower.

Last time I cringed
I was working in New Orleans, and it was so hot and muggy that they gave us umbrellas. I opened it, and when I got to the lunch tent, there was this big hairy spider on the inside of it. It’s a very rational fear!

I last said ‘I’m sorry’ …
I just guest-starred on Mom with Allison Janney, and I have severe stage fright, so I had to apologize to the cast. I’m the most neurotic person, but I own it now.
