TAMPA, Fla. -- Buccaneers quarterback Tom Brady announced Friday that he and wife Gisele Bundchen have finalized a divorce, ending 13 years of marriage and months of speculation about marital strife.

Brady posted on Instagram: "In recent days, my wife and I finalized our divorce from one another after 13 years of marriage. We arrived at this decision amicably and with gratitude for the time we spent together. We are blessed with beautiful and wonderful children who will continue to be the center of our world in every way. We will continue to work together as parents to always ensure they receive the love and attention they deserve.

"We arrived at this decision to end our marriage after much consideration.

"Doing so is, of course, painful and difficult, like it is for many people who go through the same thing every day around the world. However we wish only the best for each other as we pursue whatever new chapters in our lives that are yet to be written.

"And we kindly ask for privacy and respect as we navigate what is to come in the days and weeks ahead. Thank you."

The couple share two children, Benjamin, 12, and Vivian, 9. Brady also has a son, Jack, with actress Bridget Moynahan.

Bundchen struck a similar tone in her Instagram post announcing the couple's divorce.

"The decision to end a marriage is never easy but we have grown apart and while it is, of course, difficult to go through something like this, I feel blessed for the time we spent together and only wish the best for Tom always," Bundchen's read in part.

The Bucs lost to the Baltimore Ravens Thursday night 27-22 -- their fifth loss in the last six games -- and Brady sat at his locker looking despondent as teammates Blaine Gabbert and Ryan Griffin and quarterbacks coach Clyde Christensen tried to comfort him.
