Could this be a sign of some serious trouble in paradise?!
JM was snapped indulging in retail therapy on Sunday, while his glamazon other half walked the red carpet and attended the awards show solo!
We're puzzled as to why this couple wasn't joined at the hip, but hopefully John caught his Katycat's magical opening number on the TV!

Everyone deserves a break, right?!
