Vanessa Lachey's priorities have changed now she's a mother

She told PEOPLE.com: "It's [motherhood has] changed my priorities and it changed everything for the better. Everything now is about my kids and my family."

Meanwhile, the brunette beauty has fallen in love with her baby daughter's little smile and is enjoying interacting with the tiny tot.

She explained: "She's starting to do the facial recognition, the smile, and it's killing me. I say, 'Hi Brooklyn,' and she smiles back and I love it. I love it because I know she knows she sees me."

And Camden seems to be coming to terms with his new sister.

Asked how he's adapting to life as a brother, she joked: "I've heard some horror stories. He's the best. He's awesome."

Nick and Vanessa started dating in 2006 after she appeared in the singer/songwriter's music video for song 'What's Left of Me' and despite breaking up in June 2009, they got back together just four months later and went onto marry in July 2011.

Nick, 41, was previously married to Jessica Simpson for four years but he recently revealed he is not "in contact at all" with the singer.
