Kelly Clarkson may be a massively successful recording artist, but that doesn't mean she always had it easy.

During Thursday's episode of her popular daytime TV talk show, the 38-year-old star opened up about entering the limelight via "American Idol" in 2002 when she was crowned the show's inaugural champ in a chat with actress Jennifer Love Hewitt.

The singer recalled meeting Hewitt, 41, when Clarkson was first coming on to the scene with a few of her fellow contestants.

"You probably don't remember this, but it stuck with me so long, like for almost 20 years now ... it was at some kind of MTV Awards or VMA [Awards], I don't know what it was, but you ran up to me and it was right when [we were down to] the final three of 'Idol,'" Clarkson said. "We were just so slammed and everything was happening in a whirlwind."

The "Since U Been Gone" songstress then revealed that "people were really mean to us because we're from a talent show and it was the first season."

She reiterated that "everyone was so rude" including people on the red carpet and at the show itself.

"It was so bad. It was a horrible experience," Clarkson admitted, but interaction with Hewitt helped to ease the pain.

"You came up to me and ran up to me out of nowhere and were like, 'Oh my gosh, I'm really rooting for you'," recalled the star. "You told me: 'Please keep the ones you love so close and it'll end up being about a few people in your life, unfortunately, but this business can be really hard and just remember to keep those people that really love you."
