10 Things You Didn't Know About Maggie Pierce

As far as Grey's Anatomy characters go, Maggie Pierce is pretty much considered fresh blood! She's especially new compared to other main characters, like (obviously) Meredith Grey, Alex Karev, and even her potential new love interest for Grey's Anatomy Season 14, Jackson Avery. But it didn't take long to fall in love with Meredith's (other) surprise half-sister and the woman who plays her, Kelly McCreary. So, here are ten things you didn't know about Grey's Anatomy's Maggie Pierce and Kelly McCreary!

1. Shonda Rhimes Planned A Richard-Ellis Love Child Since The Pilot Episode Of Grey's Anatomy

In an interview with The Hollywood Reporter, Shonda Rhimes said, "I knew the Richard-Ellis love child was a storyline since I planned the pilot. I was like, 'At some point, we're going to have the Richard-Ellis love child.'"

Whoa, what?! She was planning a secret half-sister for Meredith, even before Lexie! Honestly, that's mind-blowing, considering many fans believed Maggie to simply be a replacement, Lexie Grey.

2. Kelly McCreary Began Her Acting Career In Theatre

So, Kelly began her acting career on when she made her Broadway debut in 2008. Recently, in an interview with, Kelly revealed that she has been back on stage, performing at Esther Mills in Intimate Apparel between filming Grey's Anatomy. Nice!

3. Kelly McCreary Quit Acting Before She Was On Grey's Anatomy!

Kelly's acting career wasn't always smooth sailing. In an interview with Buzzfeed, Kelly revealed that getting rejected as an actor took its toll on her and she eventually realized she didn't enjoy it anymore. So, she made a list of all the things she would do if she weren't acting. The first thing on the list was learning Spanish, so she "quit acting, and moved to Spain" to work on a farm! Now that's a big move!

While we are definitely happy that Kelly eventually returned to acting to become Maggie Pierce on Grey's Anatomy, her journey has certainly been incredible and inspiring.

4. Kelly McCreary Was Already A TV Doctor On The CW's Emily Owens M.D.

It looks like Maggie Pierce/Kelly McCreary was always destined to be a doctor! She played Tyra Dupre, and even if the show didn't last, it definitely opened McCreary up to more projects in television! And we're super happy she did!

5. Kelly McCreary Had A Small Part In Shondaland's Scandal

Shonda Rhimes certainly liked to reuse actors in her shows! Luckily she has so many! But, Kelly appears in two episodes of Scandal as Clare Tucker in Season 3. And word is, Kelly did so well in her role on Scandal that word got back to Shonda!

6. When Kelly McCreary Auditioned For Maggie In Grey's Anatomy, She Thought Her Name Was Claudette

LOL. WHAT? Just imagine Maggie's name being Claudette in Grey's. Hilarious. But, Kelly revealed to Buzzfeed that she was shocked when she got the part and got to set. She said, "Claudette was not my character's name. I was, like, Wait a minute, what the hell is going on?"

7. Richard Webber Helped Calm Kelly's Nerves In Earlier Episodes Of Grey's Anatomy

In the same interview with Buzzfeed, Kelly said, "My earliest scenes were with Jim Pickens, who plays Webber. And he really is as warm and kind as the chief comes across. And by the way, he's a phenomenal actor, and in those early days of nerves, it was a perfect environment to warm into the character and warm up myself in the world of Grey's."

That's so adorable! They already established that mentor-mentee/father-daughter bond off set. Talk about perfect!

8. The Start Of The Maggie-Meredith Relationship Was Nothing Like Kelly And Ellen Pompeo's Relationship

So, we all know that Maggie and Meredith had an awful and rocky start. But, luckily, their off-screen relationship was much nicer to say the last. Kelly revealed that Ellen "made it very, very clear to me that her trailer door is open, and she's available to talk and work on stuff with."

9. Maggie Pierce Could Have Only Been A Guest Star On Grey's Anatomy

So, when Maggie was first introduced, she was only considered a guest star. But soon after, in the fall of 2015, she was promoted to a series regular! And we're super happy that she has stayed!

10. Maggie Pierce's Entrance Was A Shock To Everyone

Shonda introduced Maggie in the most Shonda-like way ever! She told Kelly that she was the love child of Ellis and Richard, but she introduced Kelly to the table read for the Season 10 finale as the guest star of the episode.

Kelly told Buzzfeed, "I read along with everybody else, and I didn't actually know what was coming because it was a cold read for everyone. We're all flipping through together and when we reached that moment where Maggie said, 'Yeah, my mother's name is all over this hospital. Ellis Grey — did you know her?' I remember looking across the table, and the first faces I saw were Jesse Williams and Sara Ramirez, and they were, like, 'Ohhhhhhhhhhhhhhhh!' There was just this cacophony for a good 30 seconds to a minute. I just was sitting there, like, 'Heehee!'"
