Zosia Mamet and Lou Diamond Phillips will both guest on season 4 of You’re the Worst, creator Stephen Falk announced at the Television Critics Association’s press tour on Wednesday.

Girls star Mamet will play Heidi, Gretchen’s (Aya Cash) estranged best friend from childhood with whom she reconnects while back in her hometown visiting her family. Phillips, who just landed a guest role on Brooklyn Nine-Nine, will appear as himself in the role of a man who dated Lindsay (Kether Donohue) and Becca’s (Janet Varney) mother in the ’90s and was a father figure to them. Lindsay and Becca track him down in an attempt to find out why he abandoned their family.

According to Falk, Mamet’s character is “an old figure in Gretchen’s life who runs a rollerskating rink. So there’s a lot of rollerskating. Lou Diamond Phillips plays a figure in Lindsay and Becca’s former life that does not roller-skate, but has a weird relationship with lemons.”

You’re the Worst will return Wednesday, Sept. 6 at 10 p.m. ET on FXX.
