Polizzi, 24, confirmed this week she is three months pregnant and engaged to Jionni LaValle, her boyfriend of more than a year.
"I think for Nicole, I can see her having a cheetah or zebra print-themed wedding because she loves animal print," Giancola told E! News. "I'm excited for them. I just can't wait to party for the wedding and do all the fun things she has coming in her life now."
Giancola went to say she thinks one-time party girl Polizzi will be a "fun parent."
"It's not like she's 16 and pregnant," she said. "She's doing her thing, she's living her life and I just think she's blessed. I can't wait to see a little guido or guidette running around. I just think it's going to be so exciting."
