We can’t wait to see all three new stars in action when The Real Housewives of New Jersey Season 6 premieres in July. But it may take viewers an extra hot second to differentiate Teresa Aprea from Nicole Mauriello, since they're identical twins.

The twins are beautiful women now, and they both have kids of their own, but there was a time when they were just the cutest little ones you could imagine. Nicole shared the throwback photo shown below in the wee hours of June 12, writing, "Good night you all ! Sleep well ! This made me giggle before bed teresaA_RHONJ @Bobby247 #luvtolaugh"

The Bobby tagged is Nicole’s boyfriend, Bobby Ciasulli, who had a clever reply for the photo:

"Teresa was in training at the young age of diaper, for hair pulling. #twinhairpull, you have to Love it."

Yep! Speaking of hair pulling, that’s a bit of a teaser for Season 6, which includes some hair pulling action with the other newbie, Amber Marchese. (Watch the promo below.) The three new H'wives were introduced into the season as friends, but the previews hint to some tension between the twins and Amber — especially Teresa vs. Amber. It could be fun to watch.

In Teresa’s Bravo intro video, Teresa said she’s “the bitchier twin” and Nicole agreed. But in Nicole’s own intro video, she said, "Teresa is my best, best friend. She always had my back and I always had her back. Don't mess with the twins."

We wouldn’t dream of it!

Catch the Real Housewives of New Jersey Season 6 premiere on Sunday, July 13, 2014 at 8 p.m. ET.
