This story contains spoilers for Season Three, Episode One of "And Just Like That ... "

Season 3 of "And Just Like That ... " has finally dropped and fans might be surprised to discover former talk show host Rosie O'Donnell making her return to the small screen in the first episode.

When viewers last saw the "Sex in the City" alum at the end of Season 2, Carrie (Sarah Jessica Parker) was forging ahead with her long-distance love affair with former flame, Aiden (John Corbett), Charlotte (Kristin Davis) was thriving in her new career as an art gallerist and Miranda (Cynthia Nixon), was rebounding after having broken things off with Che Diaz (Sara Ramirez).

The newest episode of the HBO series, titled "Outlook Good," finds the long-time friends enjoying drinks at the bar and a young patron seemingly flirting with Miranda. Embarrassingly, it turns out that she's Brady's (Niall Cunningham) former babysitter just saying hello. Just when it seems that all hope is lost, Miranda meets Mary (O'Donnell), a fellow single interested in a hookup.

The pair end up going home together and in the aftermath, Mary reveals that Miranda is "her first," as in, ever.

The reason she's never been with anyone before? Mary's a nun. Even worse, she's a tourist.

Wearing a "Wicked" t-shirt and bearing "monogrammed" M&M's from the M&M store (standing for Miranda and Mary, naturally), Mary later meets up with Miranda in Times Square where Miranda tries to gently let her down, imploring her to not "leave God" just to be with her.

"Miranda, I would never leave God ... we're married," Mary replies, before sending her off by singing a few bars of "For Good," from the Broadway classic.

In a recent post on Instagram, O’Donnell commented on her experience on "AJLT," writing “had such a wonderful time on set — everyone is amazing.”

During an appearance on Radio Andy, Andy Cohen's SiriusXM radio show, Nixon talked about O'Donnell's performance on "AJLT," saying, "She was so centered and wonderful, so real and tender and hopeful. She was just amazing."

During the interview, Nixon also said that "AJLT" showrunner, Michael Patrick King, has written parts for O'Donnell in every season of the show thus far, hoping to entice the comedian to sign on.

"Finally we snagged her for the pilot of Season 3," she said.

The cameo is one of just a handful of TV appearances O'Donnell has made since her Emmy-winning talk show ended in 2002, including a recent turn on "Hacks," in which she plays herself, offering words of wisdom to fellow comedian, Deborah Vance (Jean Smart).

O'Donnell notably made headlines after relocating to Dublin earlier this year, posting on TikTok that she and her 12-year-old daughter, Dakota (whose nickname is Clay), left the U.S. in January, citing, "It’s been heartbreaking to see what’s happening politically and hard for me personally as well," she said.

In the same post, the "League of Their Own" actor said she'd consider returning "when it is safe for all citizens to have equal rights there in America."

In addition to Clay, O'Donnell has four other children, Parker, 30, Chelsea, 27, Blake, 25, and Vivienne, 22, as well as four grandchildren.

“I’m happy. Clay is happy. I miss my other kids. I miss my friends. I miss many things about life there at home and I’m trying to find a home here in this beautiful country," O'Donnell posted of moving to Ireland.
