In the sneak peek, the mom of 14-year-old twins Mady and Cara, and 11-year-old sextuplets Leah, Collin, Aaden, Joel, Alexis and Hannah, is sunbathing in a purple plunging bikini top, and printed bottoms.
Her mommy-time was soon interrupted when the kids found a crab in their cabana. "What an amazing habitat!" Gosselin told the kids.
The “Kate Plus 8” special continues with the sextuplets' birthday on Tuesday, June 30 on TLC.
