The 33-year-old fashion mogul will spend the holiday with her fiancé Eric Johnson and their two kids in Boston this year, where the former footballer is from, according to Us Weekly.
The family of four was spotted out and about in the chilly city Monday grabbing lunch, with Eric carrying their daughter Maxwell inside of the restaurant on his hip. Meanwhile, Eric's dad toted their baby boy Ace as they made their way in.
According to the mag, Jessica and Eric also made time for a date night, grabbing dinner at Zebra's Bistro and Wine bar Tuesday.
Prior to their Thanksgiving trip, Jessica's fiancé and their little ones took their first public family photo at an event for Jessica Simpson's clothing line at Dillard's in Dallas, Texas.
