Jessica Simpson's daughter is a ''total mommy's girl''.

The 'Fashion Star' mentor often takes her adorable seven-month-old daughter Maxwell on set with her and crew members say the tot is never happier than when she's with her mother.

A source told Us Weekly: ''Maxwell is a total mommy's girl. She just wants to be held by Jessica. Jess is really cute with Max. The baby is adorable and never disruptive.

''Jessica loves being a mom, she really is overjoyed.''

Meanwhile, Jessica's mother Tina says Maxwell is just like the singer was at her age.

The insider added: ''For Tina it's like going back in time. Maxwell is exactly like Jessica was.''

Jessica, 32, is reportedly expecting her second child with her fiance Eric Johnson, only a few months after giving birth in April.

A source revealed: ''It definitely wasn't planned. But yes, Jessica is pregnant again.''
