The former couple were both pictured at the glitzy event, however it seems they kept away from each other at London's O2 Arena.
Kym arrived at the NTAs with her Coronation Street co-stars and stuck close to Antony Cotton as she greeted fans and posed for pictures outside.
Jamie, meanwhile, who was sporting a thick beard, turned up with the EastEnders gang and wasn't on the red carpet at the same time as his ex-wife.
Earlier this month, Kym and Jamie were reportedly granted a divorce following their recent marriage breakdown.
The pair, who got together in 2008, tied the knot in September 2012 and are parents to two-year-old daughter Polly.
Both Jamie and Kym tweeted about the NTAs in the hours before the event kicked off, however they did not mention each other.
Kym said: "NTAs tonight!! Hoping we win big!! COME ON CORRIE!!!!!" Jamie told his followers: "Good luck to everyone tonight at the NTAs!!!"
