Ferrera, who admits she's not the best with (celeb!) names, chatted with PEOPLE this week about "one last thing" ...
Last song I sang
I am incessantly listening to Beyoncé's album, so "Flawless." I just sing out loud all day. I'm not saying I'm good at it, but if we are in a conversation, I might just sing my responses to you.
Last time I was embarrassed
Oh, I recently called a very famous person by a different name. I can't tell you who, but it was someone whose name I should have known. I was close, same first name, wrong last name. He was very nice about it.
Last back rub I gave
My hands strangely are not very strong, so I'm not a very generous rubber [laughs]. I would like to reciprocate; I'm just not very good at it. People are like, "Okay, thanks, you can stop now."
Last time I was impressed
Just this morning about how many people showed up for my spin class. But then the instructor was so amazing. This is actually a way of saying I was impressed with myself for getting up at 7:30 and taking a spin class!
