Heidi Montag and Spencer Pratt kept everyone guessing at the The Hills finale after party Monday night.

Montag, 21, appeared at the Los Angeles club Area without her engagement ring and without Pratt, 23, triggering fans to call out: "Heidi, where's the ring? Heidi, where's Spencer?"

As Montag flashed her ring-less finger for photographers, another fan called out, "You're better off without him!"

Fans may have to wait until season four for more details on the couple's tumultuous romance as Montag was mum on the red carpet.

Costar Elodie Otto (who says she feels accurately portrayed on the reality show and insists she's no longer mad at Montag) offered her opinion to PEOPLE. "The thing that I don't know that's real or not is Heidi and Spencer's relationship. To me they don't really look in love, so we'll see."
