Things have changed quite a bit for Vanessa and Nick Lachey since their MTV Spring Break days.

Vanessa, 36, shared on Instagram that she and her 43-year-old husband had taken their three children -- Camden, 4, Brooklyn, 2, and Phoenix, 3 months -- on a beach vacation. "Yup...day complete," she captioned a photo of herself kissing Phoenix, while Nick played with their other two kids in the sand and surf. "For sure a GOOD day!"

While Vanessa, a former MTV VJ, spent lots of quality time with her kids, she also made sure to start the week out with a little cocktail. "#SpringBreak Monday's are A-OK!!! #Casamigos," she captioned a photo of her margarita, which included George Clooney and Rande Gerber's tequila.

The Lacheys aren't the only ones celebrating #SpringBreak. Pink also recently shared a snap of her 3-month-old son, Jameson,​ during a family vacation. Check out the cute pic:
