The Real Housewives of New Jersey Season 6 premiere is less than a month away, and it looks like at least one of the new cast members is fitting in well with the veterans.

Nicole Mauriello, one of the new twins, was previously seen out on the town in a photo with Melissa Gorga, and now Nicole is back in another photo with RHONJ’s Kathy Wakile and her sister, Rosie Pierri. Kathy shared the photo shown below on June 20, writing, “Have some fun celebrating @RosiePierri birthday w/ @RHONJTwins @abbeyfeiler @richardwakile @tomkober @Bobby247."

Yep, it was Rosie’s birthday. Happy belated b-day!

Nicole’s Twitter handle is @RHONJTwins, and the Bobby copied is her boyfriend, who also seems to fit right in with everyone. Rosie shared another pic with her friends, writing, “Yes! @Bobby247: Sexy Day at the Beach with @Bobby247 @RosiePierri @RHONJTwins KEEP IT SEXY BABY #sexybeach #RHONJ.”

Rosie seemed to have a great time, which is the most important thing when it’s your day. She shared this other happy pic, writing, “At the beach with @abbeyfeiler What a great vacation & what a great Birthday.#47yearsyoung.”

Congrats! Life begins at 47, right? RHONJ fans can expect to see Rosie and Kathy part-time on Season 6, which will feature Nicole, her twin sister Teresa Aprea, plus Amber Marchese as the three new cast members.

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