Even though she's taken the "T" out of her GTL routine, mama-to-be Nicole "Snooki" Polizzi has an extra-special glow about her these days.

On Monday, Snooks shared a photo of her posing next to her fiance, Jionni LaValle, on Instagram. The couple even color-coordinated for the image; LaValle sported black cargo shorts and a black and white t-shirt, while the pint-size Jersey Shore star's baby bump looked bigger than ever under her stunning, strapless white dress.

The usually loquacious MTV star didn't have much to add to the sweet portrait, captioning it simply, "My family."

Due this fall, Polizzi, 24, confirmed to USA Today in July she and LaValle had settled on a name for their first child together, a son: Lorenzo.

The duo can't wait to welcome their little guy into the world -- and Polizzi has said she's also excited to show off her parenting skills.

"I can't wait to meet my kid!" she told V earlier this year. "Everyone will be surprised to see a different side of me. I'm loving, caring, sensitive, protective and very maternal, no matter what people might think."
