This season, Miriam Shor (who plays Diana Trout, Liza's boss) will make her television directorial debut with an episode to air in July.
And Charles Michael Davis who plays Kelsey's ex and work rival, Zane Anders, joins the cast as a series regular.
Season four ended with Josh marrying his girlfriend Claire in Ireland just hours after trying to rekindle his relationship with Liza, so we can expect to see the fallout from that.
And now that Kelsey has accepted Liza's secret, will anyone else find out?
And what about Liza and Charles? Guess we will have to wait until June!
