The two reunited over yoga of all things and shared the photo on social media, sparking return speculation.
"Andy brought her up at the reunion, so it sparked something up inside me," Teresa told E! News after they said Namaste. "So I reached out to her on Twitter and she responded. I asked her if she was into yoga and she said of course, so I said, 'Let's take a yoga class together.' So we did.
"Like I said, I've never had a problem with her, I would love for her to come back," said Teresa. "My thing is, I said what I had to say and that was it. It never went beyond that."
E! News also reports that Teresa Giudice will return for the upcoming season as will her sister-in-law Melissa Gorga and season seven additions Siggy Flicker and Dolores Catania.
Danielle left the show after the second season and a sitdown with then-costar Caroline Manzo where they called each other "garbage" and "clown." Since departing the show she hosted the series Social and appeared on Famous Food opposite Jake Pavelka and Heidi Montag.
When Teresa and Danielle tweeted their photo, Real Housewives guru Andy Cohen weighed in with, "Wowza!"
Previously, Andy said anything was possible with the Real Housewives and that he would "never say never" about Danielle returning to the Garden State.
"The Housewives are like the mafia, once you're in you're in. I always love the idea of a dramatic return," Andy told us in August 2016. "It's really cool. I think if you look at OC at the end of the season we're always kind of having former Housewives at least come back for a cameo at the end of the season."
Last month Andy Cohen revealed that Staub “is in discussion” to make a comeback for Season 8. “We are casting Jersey right now,” he told Hollywood Life.
