Ashlee Simpson is finding it hard being a ''working mom.''

The 34-year-old singer has admitted she's really struggling to find the balance between caring for her two children - Bronx, nine, whom she has with ex-husband Pete Wentz, and three-year-old daughter Jagger, whom she has with spouse Evan Ross - and recording music, filming her show and managing her fashion line.

Speaking on her reality TV series 'ASHLEE+EVAN', she said: ''Music is a career by itself, having a clothing line is a career by itself, having a shoe line is a career by itself, being a mom is a career by itself. It's definitely overwhelming.''

The blonde beauty even asked her own mother Tina how to find the balance.

Tina replied: ''I think if you're doing what you love and your passion shows through, that's all that matters. The key to it is that you find what works for you and your family and then you'll find that success.''

However, luckily, Ashlee is able to lean on her husband Evan for support.

He said: ''It's hard when both parents are working, 'cause we're trying to find a way to both be there for the kids as well as work.

''I've had to change certain schedules during my day and so now I've gotta pick up the slack and go pick Bronx up from school...which is amazing 'cause, I'm definitely the youngest dad at his school. So I look swaggy.''

And the couple look set to have their hands full even more over the next coming months as Ashlee's sister Jessica is pregnant with her third child.

The 38-year-old actress and singer already has daughter Maxwell, six, and son Ace, five, with her husband Eric Johnson, but revealed last month that the couple - who married in 2014 - are set to add a baby girl to their brood next year.
