Will & GraceThe "Will & Grace" revival is like any other reunion: a hotbed of selfies.

Now that Harry Connick Jr.'s is back on set, the actor's cast mates have been busy snapping photos with him. The actor is reprising his role as Leo, the doctor Grace (Debra Messing) married, divorced, and had a daughter with in the sitcom's original run. Both Messing and co-star Megan Mullally (Karen) were so excited by his return that they just had to celebrate with Instagram posts, as did Connick Jr. himself.

"This one," Mullally wrote Wednesday of Connick Jr. "SUCH A GREAT GUY. so fun to be around. we love you @harryconnickjr welcome back!"

Meanwhile, Messing was equally excited to welcome back her character's complicated love interest.

"Time to swooooooonnnnn. Yup! He's backkkkkkkkkkkk," she wrote Tuesday. "That southern gentleman that stole all of our hearts- @harryconnickjr . There will never be another Leo."

For his part, Connick Jr. seems to happy to be back. He shared two videos of himself playing piano with Sean Hayes (Jack) on Wednesday, jokingly hinting at romance between their characters.

"Are jack and leo dating in the new season? plot twist!" he wrote.

We're still unclear on how Leo's character will be involved since the revival will ignore the original "Will & Grace" series finale, but that's not something we'll worry about now. After all, we're reunited, and it feels so good!

"Will & Grace" premieres Sept. 28 at 9 p.m. ET/PT on NBC.
