Tony Romo faces online criticism over his joke about Tom Brady's supermodel wife Giselle Bündchen

Former Cowboys quarterback Tony Romo saw some online blowback after he made a joke about Giselle Bündchen, the supermodel wife of superstar quarterback Tom Brady.

The quip came after Brady made NFL history during a game between the Tampa Bay Buccaneers and the Chicago Bears on Sunday. Romo was one of the announcers for the CBS game.

Brady threw his 600th touchdown during the game but his receiver Mike Evans handed off the ball to a fan instead of holding it for its historical significance. Romo joked as the fan, later identified as Byron Kennedy, negotiated with a Tampa Bay staffer for the return of the ball to Brady.

"Right here, he's like, 'we need that ball, that's 600,'" said Romo on the broadcast, jokingly narrating the negotiations.

"Really? So what do you want? A million?" he added.

"A date with Gisele. A date with Gisele and I'm in," Romo said in the voice of the fan.

"OK, Tom will do it. One time, you got it," he added.

Here's the video of Romo's comments:

While Romo clearly meant it as a joke, many on social media did not find any humor in his comments.

"I don't think what Romo said was funny. It was tasteless. But that's just me," tweeted Mike Freeman, the sports race and inequality editor for USA Today.

"So is anyone going to talk about how inappropriate it was that Romo thought Brady should give that fan a "day with Gisele"? @nfl@tonyromo Women are not items for trade," tweeted another critic.

"Women are still property and this was a joke everyone laughed at," replied another detractor who added vomiting emojis.

"[Gisele Bundchen] is the mother of @TomBrady's CHILDREN - have some respect @tonyromo@NFL - she's not some prize for bargaining - I found this disgusting," responded another critic.

"Gross. y'all literally pimp out your wives/SOs for memorabilia? really?" tweeted Shalise Manza Young, who wrote up her outrage for Yahoo News.

Many others on social media defended Romo and called it a harmless joke.

Kennedy received quite a lot for the ball, including "two signed jerseys and a helmet from Brady, a signed Evans jersey and his game cleats, a $1,000 credit at the Buccaneers' team store, and two season passes for the remainder of this season as well as next season."

One sports auction expert said the ball could be valued as much as $900,000, had it gone to auction.

Brady and the Buccaneers ended up burying the Bears by a score of 38 to 3 points.
