Kristin Cavallari's engagement is back on -- and so is her engagement ring!

The "Dancing with the Stars" and "Laguna Beach" star stepped out yesterday, where she flashed her ring for the first time since announcing he was re-engaged to former fiance Jay Cutler.

Cavallari was spotted wearing the same ring Cutler gave her when he popped the question the first time back in April.

After splitting in July, Kristin confirmed the new engagement yesterday on Twitter, saying "This time it's official."
