"Grey's Anatomy" has added "White Collar" alum Bridget Regan to its list of Season 13 guest stars. Meanwhile, the medical drama's love triangle involving Meredith, Maggie and Riggs is set to create more tension in the hospital as the new season progresses.

According to TV Line, Regan has been tapped to guest on episode six of "Grey's Anatomy" Season 13. However, details on the actress' upcoming gig on the Ellen Pompeo-starrer have been kept as a secret. The actress on Wednesday also shared the casting news via Twitter where she revealed the episode's title now known as "The Room Where It Happens."

"Lucky me #Greys AND @msdebbieallen #HELLO!" Regan said.

"(Also -- who else has @leslieodomjr's voice in their head singing this episode title?)"

Regan's recent TV credits also include "Jane the Virgin," "The Last Ship," "Marvel's Agent Carter," and "Beauty and the Beast." Her casting comes after the show's second episode outing which found Dr. Alex Karev being charged with felony assault for brutally attacking Andrew De Luca.

Meanwhile, fans of "Grey's Anatomy" should expect to see the Mer-Maggie-Riggs love triangle to develop into an even thicker storyline in Season 13. Although it is palpable that this is not something Maggie would find hilarious, the writers of the show seem determined to test the sisters' relationship this season. Series star Martin Henderson, for his part, has recently teased that Maggie will continue to chase Riggs in the coming weeks.

"Maggie actually starts to think that Riggs is now just playing a bit hard to get," the actor told Entertainment Weekly.

"So it's this farcical triangle where nobody's believing the other person. Everyone's got these mixed intentions, and they're all getting bundled up, and no one really knows who likes who for what reason. So it continues to actually become quite funny."

"Grey's Anatomy" Season 13 airs every Thursday at 8PM on ABC.
