G revealed her childhood crush on the rapper when she happened to get on the same elevator as Robert Van Winkle (aka Vanilla Ice) while he was in the middle of giving an interview to WNBC's New York Live.
"What is up? Oh my god, I was obsessed," Giuliana said, and she wasn't kidding—Mama DePandi can vouch for her daughter.
"What's up, E! News? Oh my gosh, I was so excited running into Vanilla Ice, that was a dream come true. My mom used to drive me to his concerts," G excitedly said, with her mother by her side, during this exclusive video.
"I remember," Mama DePandi said as she put her hand up.
"She loved him, too, so this is so exciting," Giuliana added, but Mama DePandi interjected, "No. I like chocolate." (LOL!)
Aside from gushing about her fangirl moment, Rancic has been spending time with the two most important men in her life, Bill and baby Duke Rancic. The E! News host posted an adorable photo of the duo at Washington D.C.
"Flying high with @BillRancic and #babyduke in my hometown. #DC," Rancic wrote with the picture.
