We can go on and on about how we wish Pretty Little Liars would bring back Rosewood hotties Noel, Lucas, and Jason, but the character we really want to see make an epic comeback is Regina Marin

Hanna's spunky grandma made her grand debut in Season 2, and in Season 3, Episode 14 ("She's Better Now"), she stole our hearts when she burst into song at the school marathon (Why? Because she could.) As much as we'd love to see Regina return to Rosewood, we're happy to see her portrayer, Betty Buckley (who also happens to be PLL director Norman Buckley's sister!), earning rave reviews for her role in The Old Friends at The Signature Theater in New York City.

The Old Friends, a world premiere play by Signature Legacy Playwright Horton Foote, tells the story of two longtime Texas farming families who receive alarming news and must "confront the issues surrounding legacy, loyalty, and the meaning of happiness that have hounded them for generations."

But unlike grandma Marin, Betty's character in The Old Friends, Gertrude Ratliff, is vulgar and manipulative. In fact, Vulture calls it "a perfect monster of a performance." 

Betty isn't the only Pretty Little Liars star on Broadway. Keegan Allen is set to make his Broadway debut in Small Engine Repair this fall. Keegan has been cast as Chad, a privileged jock who turns up at an out-of-the-way repair shop, stirring much resentment in the three former high schools buddies who frequent the establishment.

Though the play premiered two years ago in Los Angeles, this MCC Theater production will mark its New York premiere. Co-starring in the project will be James Badge Dale, James Ransone, and John Pollono (who also penned the script). Previews for the play will begin at the Lucille Lortel Theatre in Greenwich Village on Oct. 30, with the official opening coming on Nov. 18.

Meanwhile, you can catch Betty Buckley in The Old Friends at the Signature Center through October 6, 2013. 

Catch the Pretty Little Liars Season 4 Halloween special on Tuesday, October 22, 2013 at 8 p.m. ET/PT on ABC Family.
