Ashlee Simpson and Evan Ross to star in reality show

Ashlee Simpson and her husband Evan Ross are set to star in their own reality show.

The pair will give fans an exclusive look into their life as a married couple on the new show 'Ashlee+Evan', which will premiere on E! on September 9.

Ashlee, 33, married 29-year-old Evan - the son of Motown legend Diana Ross - in 2014 and the docu-drama will follow the duo as they juggle marriage, friends, family and their careers.

The first episode of the show will be a special hour-long version, followed by five half-hour episode s in the coming weeks.

Although some reality TV families have felt the effects of being recorded 24/7, Evan isn't worried about any potential negative effects on his relationship with Ashlee - the younger sister of Jessica Simpson, who herself appeared on MTV fly-on-the-wall show 'Newlyweds: Nick and Jessica' with her now ex-husband Nick Lachey.

Evan said: "I think in any relationship in this industry, there's a stress on relationships. I think that's reality, but in no way do I think that if a relationship is meant to be together and a marriage is meant to be together, that anything like a show or being in this industry can change that. I don't think any fear is coming from our relationship, which is a good thing."

Ashlee and Evan are parents to two-year-old daughter Jagger and the 'Pieces of Me' hitmaker also has nine-year-old son Bronx with her ex-husband Pete Wentz.

Ashlee recently admitted she is keen for her and Evan to have another child together.

She said: "I definitely want to have another one, for sure. I love being a mom. I mean there's really nothing greater than my kids. So, for me, that's something I continue to want to do in life."
