JASON Kelce is proving life after football really is kids’ play.

Sponsors and TV networks have been queuing up for Jason’s signature, as brother Travis ‘s similarly blossoming off-field career is also exploding into life.

Hotel chain Marriott signed up the older Kelce sibling, who quit the Eagles last year, on a $2.4 million, two-year deal.

That’s on top of a $1.8 million per season deal with ESPN, which includes an extra $1 million sign-on bonus, to work as a Monday Night Football pundit.

Meanwhile, the advertising and distribution rights to NFL legend Kelce’s massively popular New Heights were sold to Amazon’s Wondery in August for $100 million

And a well-placed source has told The U.S. Sun that toy manufacturer Spin Master is the latest company to secure Jason on yet another massive deal.

This new three-year contract is worth a tasty $950,000 a year, with a $750,000 signing bonus.

Spin Master, a “leading global children’s entertainment company,” is the creator of the popular Paw Patrol animated TV show.

They see the doting father of three girls as the perfect fit for their business and fight off competition from other brands to land Jason.

The source says many different brands in the toy industry have “been pushing to get him on board for many months now.

“He has a fantastic image, and he is seen as a superb example of being a sweet and very good father.”

“It makes perfect sense for Jason to become involved with a company like this,” the insider told The U.S. Sun.

Part of the contract stipulates Jason will make appearances at public events across the United States.

He will also star in commercials, including one for Hatchimals, which is a favorite of his kids, for Thanksgiving, Black Friday, and Christmas.

Kelce will also participate in charity functions.

“Jason is super happy with this deal,” added the source.

“t’s something that his kids love, and that is super important for him.

“He is a daddy’s girl at heart.

“He spends tons of time with the kids as he is retired now.

“He loves to play with them, do activities, and be the best dad for them.

“Even if it’s spending hours and hours playing and dressing as a princess and making them laugh with costumes and playing with toys. ”

And his relationship with brother Travis and girlfriend Taylor Swift is sure to be helping his business venture.
