Teresa Giudice Reveals the Exact Kind of Engagement Ring She Wants

In the past couple of weeks, Teresa Giudice's beau Luis "Louie" Ruelas has given her some extra sweet gifts. But as The Real Housewives of New Jersey cast member revealed on the May 12 episode of Watch What Happens Live with Andy Cohen, she just might be hoping for something even sweeter than sprinkle cookies and globe cake.

When Louie made a surprise appearance on the late-night talk show, Andy quizzed him to make sure he knows his girlfriend up and down. Spoiler alert: Teresa's love passed the test with flying colors. Well, almost.

Louie knows that Teresa prizes physical touch and that she whips up an amazing steak pizzaiola. But then, Andy dove into a topic that has more carats. "What cut of diamond is Teresa's favorite for an engagement right?" he asked, listing several options.

Alas, Louie guessed that Teresa would like a pear-shaped sparkler, but in reality, she'd go for an oval cut. "Louie, you better get that right!" Andy said. Teresa echoed Andy's response and then added: "A pear — you eat it. An oval is what I want to wear on my finger."
