Gretchen Rossi and Lizzie Rovsek Have a Very Housewives Halloween

Halloween has a way of bringing people together, and that was definitely the case at Life & Style Weekly's "Eye Candy" Halloween Bash Thursday night (October 29). Not one-- but three-- Real Housewives were in attendance to party it up in honor of the spookiest day of the year.

The Real Housewives of Orange County worlds collided when Gretchen Rossi and Lizzie Rovsek, who appeared in different seasons of the show, had a ball at the bash. Lizzie looked like one hot mama in her outfit, and it seems almost impossible for Gretchen to look any cozier than she did in her costume.

Gretchen also had her man Slade Smiley in tow at the party, who looked pretty fierce in his gladiator get-up.

The Real Housewives of Miami's Joanna Krupa also joined in the festivities at the Life & Style Weekly shindig. She looked stunning, as usual, in this glitzy dress and eye-catching headpiece ensemble.

Of course, when you have three Housewives in one room together, you've got to snap a pic of them all. Luckily, Gretchen, Lizzie, and Joanna all posed together for one epic photo.

"Girls just wanna have fun," Gretchen wrote in the caption to another photo of the trio on Instagram. It definitely looks like that mission was accomplished.
