Jennifer Love Hewitt's heart has ''expanded'' since welcoming her daughter into the world last November.

The 'Ghost Whisperer' star admits she's been overjoyed since giving birth to her baby Autumn five months ago and she can't help but smile when she locks eyes on the tot.

She said: ''I just feel like my heart expanded quadruple and every time I look at her, I just melt. It's great. And I get no sleep which is also fun.''

The 35-year-old actress also believes her husband Brian Hallisay, whom she married last year, has adjusted to fatherhood really well.

She explained to E! news: ''He's great, he handles it great. He looks at me sometimes like I'm a crazy person, especially right in the beginning when we got home with her, he was like, 'You look a little crazy.' I'm like, 'Alright, we'll talk about it later'.''

Meanwhile, Jennifer admits she often feels down about how hard it's been to lose her baby weight, but she's focusing on staying fit and healthy because she wants her daughter to grow up feeling confident in her body.

She said previously: ''If your priorities are right, the baby's most important. You have to eat to feed to your baby. And I have a girl so I want her to see some day why her mom has good self-esteem and good body issues.

''It gets you down sometimes, I'm not going to lie. I've had days where I'm like, 'Ugh, I wish this was easier.' But it's not, and that's OK.''
