Laconic Seattle Seahawks running back Marshawn Lynch remained closed-off to most outlets during Super Bowl media day on Tuesday in Arizona, but ET special correspondent Michelle Williams got him to open up in a sweet moment.

As she did with all the other players, Williams tried to get Lynch to put his golden pipes on display and join the Destiny's Child singer in singing a Katy Perry song when she caught up with him backstage, but she didn't expect a lot of participation. During his time at the podium, Lynch told reporters bluntly, "I'm here so I won't get fined."

According to ESPN, the NFL warned Lynch that he could face a $500,000 fine if he failed to make himself available on media day.

"I have to sing?" Lynch asked Williams. "I run into people, though. I think it'd be better if you sing."

Lynch eventually gave in, belting out the chorus from "Nights Like This" featured on the soundtrack of the 1991 classic The Five Heartbeats.

For his efforts, Williams rewarded Lynch with an Xbox One, which Lynch assured us was going straight to his Fam 1st Family Foundation, launched by himself and San Francisco 49ers quarterback Joshua Johnson.

"One lucky kid from my foundation will be going home with an Xbox One as soon as I get home from the Super Bowl," Lynch said. "We actually have an event going on Wednesday back at home -- a couple workshops with some kids doing some architect work, which is really good."

After the football season ends is when the real work begins for Lynch, as he returns to his hometown of Oakland, Calif. to give back to his community.

"At home during the off season I have a camp where I sponsor about 800 kids that come to a free football camp and that's just one of the events we do," Lynch said. "We've been doing work in our community for about nine years now. I actually played against three kids that came through my foundation in the [NFL]. I got about five kids that'll be entering the [NFL] Draft this year."

And he's not done yet!

"We're in the process of getting a youth development center in Oakland," Lynch added.
