Destiny's Child vet Kelly Rowland might have been a judge on the U.K. version of "The X Factor" for only one season, but during her tenure on the show, she learned enough to offer up some advice to newbie judges Britney Spears and Demi Lovato.

The singers have already been judging talent for the show's new season, and if they think the hard work is behind them with the audition rounds over, Rowland warns there is no rest for the weary.

"I'm excited for them," she told MTV News. "I'll let them know it's a lot of work. It is a lot of work, but it was definitely a great process."

Rowland, who wrapped up her judging duties at the end of the show's last season, looks back fondly on having the chance to pluck the next great singing star out of obscurity, and she said she hopes Spears and Lovato feel the same way. "You might be running into the next big thing," she said. "Or, like for Britney, the next big her, or the next big Demi Lovato. I think that's really exciting for them, and they'll be a part of that, and they'll never forget that."

Considering just how hands-on the show's judges are, Rowland notes that Spears and Lovato need to make sure they do right by their contestants. "Any advice? Take it one day at a time. It's a lot of work, but it's a lot of fun," she said. "Choose the right songs and songs that will make people excited, make them feel something ... you have to touch people's hearts.

"It is a lot of responsibility, and when you screw up or if you screw up, then everybody blames you," she noted. "Simon included."

The new season of "The X Factor" kicks off September 12.
