The 44-year-old explained, ""I'm always hoping for J.Lo to show up, just 'cause I really enjoy some J.Lo."
However, there is still no definite answer on whether a season three will even happen.
Witherspoon explained, "We want to do it, we're just kind of waiting... We're trying guys! We're trying to come up with the right story."
Dern added, "[Nicole] just texted that we have to do another one right away."
She continued, "I really do fantasize that we'll do it again because... [I] miss those characters. We're so lucky. They're just the best characters."
Nicole Kidman has also spoken up about a third season. The Australian actress told News Corp Australia: "I think we would love to do a season three because there [are] certainly ideas. But we would not do it without all of the same people involved... even the kids."
Although a third season has not been confirmed, the potential of an even more star-studded cast has definitely got fans talking.
