Jessica is spending the American holiday by Lake Austin, which is located close to where she grew up in Texas, and it seems her little family are having a lovely time.
While out on the water, the US singer captured daughter Maxwell Drew, two, and 17-month-old son Ace Knute sharing a giggle together while wearing their lifejackets.
Posting the sweet snap on Instagram, Jessica told her followers: "Thankful for these two WILD TURKEYS! #lakeaustin #maxidrew #aceknute." Aww!
It's been a busy year for Jessica, who has been juggling her huge career with motherhood and being a new wife.
In July, Jessica and former NFL player Eric Johnson married in a private ceremony in California.
The couple later released a statement saying: "We are overwhelmed with complete happiness and love having made our eternal commitment.
"To say 'I do' in front of family, friends and, most importantly, our children has been the happiest moment of our lives."
