The former Aston Villa centre-half has played a big role in the Lions' run to Wembley.
Lowry revealed to The Sun: "My mum and dad will be watching the game on telly - they're having a few friends round, so it should be quite a do. It will be 1.15am back home when we kick off, so they should be in the mood by then.
"They listen to all of Millwall's games on the club's internet site - even the midweek ones, when they get up at 3am, listen to the game and then go to work.
"They were going to come over for this game but the air tickets were so expensive.
"They have said they will come over for the final if we get there."
