Snooki's baby boy is so darn cute, even her super-busy, super-famous Twitter followers are sitting up and taking notice.

The pint-size Jersey Shore star, who welcomed Lorenzo (with fiance Jionni LaValle) in August, posed — makeup-free! — for a sweet portrait with her son Saturday, Nov. 3.

"Mommy & son," the fresh-faced brunette, 24, wrote underneath the image, in which she clutches her adorable, tracksuit-clad bundle of joy. ("I'm not just saying this 'cause he's my son, but he is the PERFECT little man," she added later. "I'm a lucky mommy.")

Nicki Minaj couldn't agree more with Snooki's assessment of her baby's cuteness. "He's beautiful snooks, congrats!!!" Minaj tweeted Saturday.

The American Idol judge isn't the only pop star congratulating Snooki on her new arrival.

After the reality show standout tweeted about her obsession with Rihanna's "We Found Love" in early September, the flattered songstress responded via the social networking site.

"Thank you!" Rihanna wrote back. "Let me know if you need a sitter."
