Brittany Cartwright sparked major rumors of an engagement during last night's episode of "Watch What Happens Live," the late-night talk show of Andy Cohen. As she sat and chatted about the events of the latest episodes of "Vanderpump Rules" with her co-star and friend Ariana Madix, Cartwright was wearing a stunning ring on the ring finger of her left hand.

During the show, Andy Cohen questioned Brittany Cartwright about her potential plans to wed and suggested she and jax taylor may already be married. Cohen also pointed out that Taylor had been seen wearing a wedding band in recent Instagram posts.

However, Cartwright didn't confirm an engagement. Instead, she claimed Taylor had been wearing a wedding band because he has the "itch" to get married.

Brittany Cartwright went on to acknowledge that it likely seemed strange for her to speak of getting married because of the current drama on "Vanderpump Rules." As fans well know, Jax Taylor recently admitted to cheating on his girlfriend after two years of dating with Faith Stowers, their friend and a regular guest star on the show. He then dissed Cartwright in a leaked audio clip, claiming he wasn't open to marrying her or getting her pregnant.
