Jessica Simpson: 'I Can Find Love Anywhere'

Just a week after admitting to brushing her pearly whites just three days a week – and getting reprimanded by her dentist – Jessica Simpson flashed her now infamous million dollar grin at New York's Operation Smile Annual Gala.

"Trust me: I've been through it," Simpson told the crowd, reflecting on her brushes with criticism and self-esteem issues. "I've had to travel from country to country but we can do it right here in America and find ourselves, believe in ourselves and be who we are."

Still, the singer, who turns 30 in July, is working on boosting her self-esteem and is optimistic about finding love again.

"It's happening and I feel it," Simpson said. "I think [30] is going to be a good year for me. I experienced a lot in my twenties – a lot more than a lot of people in their twenties would experience. I feel old in a lot of ways, but I feel naive in ways that I can't wait to see what happens next."

And despite a recent string of failed romances, Simpson, who stays svelte by boxing with her trainer, remains confident. "I can find love anywhere," she said.

During the gala, Simpson also revealed the launch of a new self-esteem initiative with Operation Smile called "A Beautiful Me, Believe in Yourself, Change the World," that seeks to improve the lives of young people.

Says Simpson: "I promise this movement will change the lives of so many girls that don't feel good about themselves.
