Happy Daughter’s Day!

At least that’s what Finding Dory star Ellen DeGeneres proclaims in a new promo for the film costarring Diane Keaton as Dory’s mom, released just before Mother’s Day this Sunday.

The new spot shows DeGeneres and Keaton wishing everyone a happy Mother’s Day, once the talk show host has been corrected by the Oscar winner. In the film, DeGeneres reprises her role from 2003’s Finding Nemo in which she plays a forgetful blue fish named Dory. “She’s been lost for a long time, and she’s just tried to act like everything’s fine,” DeGeneres told PEOPLE last year. “And in this film, you see that it’s kind of like she’s taken a little bit of a – she’s paid a toll on it.

“She misses the fact that she has a family, and she realizes she has a family,” added DeGeneres. “And where are they? Did her parents give her away? Where is her family?”

Keaton and DeGeneres are joined by Eugene Levy, who voices Dory’s father, while Ed O’Neill and Ty Burrell join the cast as Hank the octopus and Bailey the beluga whale, respectively.

Finding Dory hits theaters on June 17.
