Tony Gonzalez will watch his ex, Lauren Sanchez, wed Jeff Bezos in-person this week, TMZ Sports has confirmed.
Sources tell us the Hall of Fame tight end -- who shares a son with Sanchez -- is on the guest list for the big Bezos bash out in Venice, Italy ... as is his current wife, October Gonzalez.
The two already appear to be in the area getting ready for the extravagant ceremony -- as they've been spotted moving around all over Europe the past few days.
