Speculation among fans about a multi-Doctor reunion episode for the anniversary has run rampant in recent months, and was only spurred when Tom Baker recently said he is willing to return to Doctor Who.
McGann, who played the Eighth Doctor, was asked if he has been contacted about the 50th anniversary while speaking to The Independent.
"No," he answered, adding: "I mean, I know it's imminent but no, there's been no invites to or sounding out taking place but maybe it will happen, we don't know."
McGann went on to admit that he's not actually very familiar with the revived Doctor Who series.
"I don't have a television. No. So, I don't watch anything," he explained.
"In fact some of my mates, particularly my gay mates, they say, 'How do you live? What do you do?' I've never seen an episode of Friends. I don't know who the newscasters are... I just got out of the habit."
He continued: "[I] Never watch myself. Sometimes you're made to watch yourself... I've just about got used to the sound of my own voice, doing voice works. But actors are like everyone else, why would you want to look at yourself? See yourself leaving a room?
"But I know Matt Smith and I saw him the other day. It's in safe hands, the kid's obviously brilliant, a really, really good choice to take it on."
McGann previously claimed that he would "love" the chance to play the Eighth Doctor on television again.
Earlier this week, former Doctor Who star Noel Clarke told Digital Spy that he doesn't expect to return as Mickey Smith for the anniversary.
Doctor Who kicks off series seven on BBC One in the UK and BBC America in the US later this year with the episode 'Asylum of the Daleks'.
