Jessica dishes on her relationship with Tony

Now, she tells the June issue of Glamour, that she is "in love" with the Dallas Cowboys quarterback, whom she says helped her gain more confidence.

She says she even wrote him a song, "Back in My Old Boots."

"He reintroduced me to myself," Simpson says. "I thought that I had to be deeper, more profound and more artsy. You change with the guys you date."

"Tony taught me that because he loves me [as me]. He made me feel comfortable [being myself] again," she adds.

She dismisses critics who claimed she jinxed his career by showing up at one of his football games that he lost last year.

"Everybody takes everything out on me! But that was ludicrous," she says. "I don't understand why they think that I would be a distraction to Tony. Do they really think he can see way far up in that box? No."

She says Romo first caught her eye while she was going through her divorce with Nick Lachey.

"My family and I were watching a Cowboys game ... and — Tony would die if I told you this — but [on TV there was a story] about him," she says. "They said his celebrity dream crush was Jessica Simpson.

"My family was like, 'Did you just hear that?'" she goes on. "His picture came up, and I'm like, 'He's really cute.' Then I heard [that I was his crush], and I'm like, 'Oh my gosh!'"

They met a year-and-a-half later after a pal introduced Tony to her dad, Joe Simpson.

After Tony spotted Jessica and Joe at the Country Music Awards last November, "Tony e-mailed my dad, 'Cute date,'" Simpson reveals.

"My dad was like, 'Look what Tony said,' Simpson says. "I said, 'Give him my e-mail address. We'll see if he's good with words.' Then he e-mailed me, and we flirted over e-mail and on the phone."

She says they got to know each other "by talking, which I think is the best way." (Revisit the love lives of Jessica and Ashlee here.)

On their first date, Simpson admits, "I had butterflies that you would not imagine. I wanted to puke in the cup holder ... It took me forever to put together an outfit!"

He tried to kiss her on their first date. "I was taken aback....

"The fact that this guy, on our first date, in the first 10 minutes of dinner, wanted to lean over the table and say, 'This is my girl, and I want to kiss her' -- our first kiss in front of everybody -- was awesome," she says.

She also hints about her split with Nick Lachey, saying, "There's too much competition [being with a musician]. There's too much know-it-all pop star."
