Proudly showing off her post pregnancy body, Jessica Alba was busy soaking up the sun and enjoying time with her family in Cabo San Lucas on Saturday (December 31).

The “Sin City” beauty sported a fuchsia bandeau bikini top and grey fedora while taking a dip in the pool and playing a game of catch alongside husband Cash Warren and their too-cute daughters Haven and Honor.

Previously commenting on her post-baby slimdown after giving birth to Haven back in August of this year, Alba said, “I didn’t gain as much weight with my second pregnancy, so I think that really made a big difference.”

The 30-year-old actress added, “I did prenatal yoga up until the very end. I just made healthier choices. I started working out and not going too crazy, but I did what was safe and what the doctor approved.”

Making for quite the precious sight to be seen, Mariah Carey and husband Nick Cannon toted their twins, Moroccan and Monroe, down the streets of Aspen, CO on New Year’s Eve night (December 31).

Color coordinating their white outfits along with their little ones, the “We Belong Together” singer and her “Drumline” hubby smiled for paparazzi before disappearing inside Mariah’s mom’s Joan Boyce jewelry store prior to the evening’s NYE celebrations.

Meanwhile, Mr Cannon recently took to his website to try and offer advice to all of those out there who end up consuming one too many drinks while ushering in 2012.

The rundown of Nick’s top five hangover cures are as follows:

Hair of the Dog: Some bartenders say that the best way to get rid of a hangover is to have a cocktail. Just one or two sugary cocktails like a Mai Tai, and you’ll be back to feeling like your old self.

Vitamin Water or plain H20: Alcohol makes you dehydrated, and being dehydrated can cause headache, dizziness and dry mouth, so water is the way to go.

Soda or Coffee: Caffeine will always help with the hangover.

Kentucky Fried Chicken: Some think that greasy food like Colonel Sanders’s will absorb the alcohol out of your body with all the grease. I don’t know if that works, but any excuse to order up some KFC is fine with me.

Hit the gym: Get all the toxins out of your system by sweating it out.

Already in party mode as we approach 2012, Nicole “Snooki” Polizzi was front and center at the Palms Casino Resort in Las Vegas, Nevada on Saturday (December 31).
