Kelsey Grammer DOESN'T GIVE A CRAP about his lifetime ban from the Piers Morgan show ... telling TMZ the CNN host is so irrelevant, it's not worth his time to be upset.
We broke the story ... Kelsey became persona non grata at Morgan's show last month when he walked off the set after the network aired a pic of his ex-wife, Camille Grammer, in the opening moments ... contrary to what he had been promised.
But this weekend, Kelsey was at LAX with his wife Kayte Walsh and their adorable baby girl Faith when he told us he couldn't CARE LESS about Morgan.
Still, Grammer says he won't hold the grudge for a lifetime ... and if the circumstances were right, he might even be willing to have a chat with the guy.
Just don't hold your breath.
Kelsey Grammer's BANNED
From My Show

Move over Madonna ... Piers Morgan tells TMZ, he's got a new enemy ... Kelsey Grammer ... who's now officially BANNED from Morgan's show after walking off the set last week.
Morgan was out in NYC yesterday ... and he's clearly still pissed about last week's incident when Grammer bolted from his scheduled appearance on "Piers Morgan Tonight" -- just minutes before the interview started.
Morgan claimed Kelsey ditched the CNN show after the network aired a pic of his ex-wife, Camille Grammer, in the opening moments.
And now, Morgan's holding a big grudge ... telling us Grammer's little stunt will be his last -- because he's NEVER welcome back on the show.
FYI -- Morgan has already banned Madonna from his show ... but no one really knows why.
