Mahomes and Kelce smiled as they posed with ex-NFL passer for a photo, which Christensen shared on his Instagram story.
According to Christensen’s story, the trio worked out at Colleyville Heritage High School in Texas.
Christensen played for the Bengals, Eagles and Browns after being drafted in the fifth round of the 1983 NFL Draft.
Earlier this month, Mahomes was seen working out with new teammate Marquise ‘Hollywood’ Brown and Christensen.
In a video posted to Instagram, the former Ravens and Cardinals speedster flashed his speed as he went out for passes from Mahomes.
Brown signed a one-year, $7 million contract with Kansas City in March.
The Chiefs’ offense welcomed another receiver on Thursday when the team selected former Texas receiver Xavier Worthy in the NFL Draft.
And former Panthers star Luke Kuelchy believes Kelce will thrive with Brown and Worthy playing alongside him.
Asked on the Up & Adams show how the Chiefs will use Worthy next year, Kuelchy said: ‘You’ve go to imagine they are going to utilize that speed on some deep balls, big overs, some zoom sweeps.
‘I think the biggest winner this offseason with the Chiefs is Travis Kelce. You bring in Marquise Brown, vertical speed down the field, Xavier Worthy, vertical speed down the field.
"I think the biggest winner this offseason… is Travis Kelce."

‘So now there is going to be all these layers and space for Travis Kelce to run around more than he has been able to and catch these balls so uncontested.
‘These guys are running down the field on overs and crossers and Travis Kelce can just run underneath and catch the ball.
Kelce was his typically impressive self last season, though he failed to register 1,000 receiving yards for the first time since 2015.
