"Back to the place we first said, 'I love you,'" the 34-year-old wrote in the caption.

Fans quickly flooded the brunette beauty's Instagram post with comments congratulating her and Brian on their engagement, but since the photo was posted on Saturday, April 1, other fans were skeptical about it being an April Fool's joke.

"Is that your fake ring or is it real?" one fan asked excitedly, with two pink heart emojis.

The commenter was referring to an interview that Kristen did last May when she admitted that she was wearing a "fake" engagement ring. Kristen and her Pump Rules co-stars Katie Maloney, Scheana Marie, and Stassi Schroeder all did a joint interview together where they gushed over Katie's nuptials to castmate Tom Schwartz.

But during the interview, the ladies called Kristen out for wearing a stunning diamond ring on her left finger even though Brian hasn't proposed to her yet — and Kristen owned up to it!

"I do," she told E! News. "I bought it for myself, I just want to test it out, you know? I just wanted to see, what if I don't like this cut?"

It seems like her engagement photo on Instagram was just part of an April Fool's prank because she posted another photo a few hours later, showing off her bare left ring finger.

But even though Kristen and Brian haven't taken the next step in their relationship, it seems like things are going great for the couple. They current live together and they even are pet parents to an adorable Yorkie named Gibson.
