Bezos posted pics of him and Sanchez looking super affectionate as they partied by a pool in St. Barts.
Now here's what's interesting. Check out this pic of Jeff with Lauren's son Nikko and Nikko's dad, former NFL star Tony Gonzalez. Tony was married to Lauren, and we're told Tony and his wife are vacationing with Lauren and Tony ... and we're told that's not the first time.
Jeff posted that 2022 will be a time for personal growth. For her part, Lauren commented and wrote, "I love you baby. For every reason and no reason."
You gotta check out Bezos's duds ... an orange patterned vintage '70s shirt, cream chinos and shades.
Lauren's was a little more current ... a black crop top and black leather pants.
The 57-year-old's going through -- well, some might say a mid-life crisis -- as he showed off his buff bod, and our Bezos sources flatly denied its the result of HGH, despite what some speculated on social media.
