Rory McIlroy probably isn't leaving the PGA Tour for an appearance on American Idol anytime soon.

McIlroy and Shane Lowry celebrated their Zurich Classic victory on Sunday by belting out Don't Stop Believin' in a makeshift karaoke session:

The duo earned their right to celebrate with a late charge in Sunday's final round of the team competition. They birdied six of the final 12 holes to bring their tournament score to 25-under and force a playoff with the pairing of Chad Ramey and Martin Trainer.

Both pairs then played the par-five 18th hole as the tiebreaker, and McIlroy and Lowry caught a break when Ramey and Trainer shanked multiple shots on their approach to the green. The victors didn't exactly play the hole to the best of their ability, with Lowry hitting their second shot into the sand trap and then missing a birdie putt that would have won it.

Still, Ramey and Trainer bogeyed the hole, which clinched the win for McIlroy and Lowry.

And also led to quite the singing performance from the duo.
