Oh, those "Drop Dead Diva" folks can be sneaky (and we like it). As Zap2it reported first, Paula Abdul has already shot a scene that will potentially open the still unannounced Season 3 on Lifetime. 

Now the network tells us that Rosie O'Donnell is appearing in tonight's (Sunday, August 15) episode airing at 9 p.m. ET. And Lifetime is keeping the details under wraps!

O'Donnell makes a surprise return to the show, reprising her role as Judge Madeline Summers to help lawyer Jane Bingum ( Brooke Elliott) resolve a difficult case. 

The network is keeping the details of O'Donnell's appearance close to the vest. She filmed the additional footage during her last guest stint on the series.

O'Donnell recently made headlines with the announcement that she's returning to talk TV on Oprah Winfrey's OWN network.

Watch a preview of Sunday's episode below:
