Age really is just a number!

Kate Gosselin turned 40 in front of the cameras for her reality TV show, Kate Plus 8, so everyone could enjoy her birthday bash. The mom of eight turned heads in the cleavage-baring bikini she wore on the beach in Mexico while celebrating with her kids at the Generations Riviera Maya by Karisma. With her bikini bod, you'd never know she had eight children! All of that running around certainly has kept her in tip-top shape.

Her swimsuit was solid purple on the top and a mixture of bright colors on the bottom, which put all of her assets on display.

Although she and a gal-pal hit the beach with her brood to take some time off from their busy schedules and relax, Gosselin seemed to do everything but sunbathe! She and her kids found a crab in the kids' cabana. Everyone gathered around to check out the ocean creature and even made a habitat for it, which probably isn't on their normal to-do list LOL.

The final result led to a temporary new home for the baby crab. "What an amazing habitat!" Gosselin told her kids, upon seeing their creation.

"It was comfortable," Gosselin said on her show. "It was the relaxation that I needed after that busy trip."

All of Kate's kids, Cara, Madelyn, AlexisHannahAaden, Collin, Leah and Joel, traveled with the Celebrity Apprentice alum to celebrate her birthday. They even got together to make their mom some cakes at the resort's Little Eko Chefs kitchen in honor of turning the big 4-0. Apparently, she wasn't too excited about the milestone birthday, because Leah joked that a certain candle wouldn't be well received LOL.

"She's not going to like the fact there's a 40 on it," Leah said. "But she can deal with it."

They presented the cakes to her at a private birthday lunch at Habb Mediterranean Restaurant and Lounge.

It's the thought that counts after all!

But when she isn't soaking up the sun on the beach in Mexico, Gosselin is busy hanging with her millionaire boyfriend, Jeff Prescott. Although she doesn't seem ready to go public with him just yet, they were spotted out on a date in Philadelphia a few weeks ago.

Sources told E! News that Gosselin and Prescott enjoyed a romantic date together at Talula's Garden in Philadelphia. While the pair seemed to be enjoying each other's company and even shared a kiss, our source revealed that they weren't displaying too much PDA.
