Lady Gaga asks Matt LeBlanc the Sophie's Choice of 'Friends' questions

Lady Gaga is having the week of her life!

After releasing her amazing album, "Joanne," to performing on "Saturday Night Live," she stopped by "The Late Late Show with James Corden" for even more fun. After participating in probably the best Carpool Karaoke yet, Gaga sat in with Corden's band where she decided to ask Matt LeBlanc a very serious question.

The actor was up for anything when Gaga asked the ultimate Sophie's Choice of "Friends" questions, "Who would you rather? Monica or Rachel," and he literally had the most Joey Tribbiani answer ever. "I would have me some Phoebe...she's very bendy."

Check out the hilarious question and answer in the video below!
