In the new Us Weekly, Nicole "Snooki" Polizzi tells Us all about her pregnancy and engagement to Jionni LaValle -- and acknowledges her inevitable critics. "I don't care what anybody else thinks," the reality star, 24, says.

And Snooki's Jersey Shore roomie Sammi "Sweetheart" Giancola was quick to defend her pal's baby news.

"It's not like she's 16 and pregnant," Giancola told E! News of the once hard-partying star. "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."

(Indeed, Sammi would be welcome to babysit Snooki's baby-to-be, Snooki told Us.)

"Snooki is going to be a fun parent," Sammi said. Some gift ideas? "If it's a boy maybe some hair gel. . . If it's a girl, maybe some baby bronzer. I think it's definitely going to be Jersey-themed."

Sammi also envisions an over-the-top wedding for Snooki and LaValle, 24. "I think for Nicole, I can see her having a cheetah or zebra print-themed wedding because she loves animal print. . .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."
