They have been engaged for two years, and Jessica Simpson has revealed she and Eric Johnson have set two separate wedding dates.
However the star admitted that she hasn't had the opportunity to walk down the aisle - because both times she then fell pregnant.
'We've had two different wedding dates, but he keeps knocking me up,' she said when she appeared on The Tonight Show with Jay Leno on Tuesday night.

'We're doing it very backwards, I know... I'll just keep my legs crossed, I guess, this time.'
The 32-year-old, who is pregnant with her second child and confessed it was not planned, displayed her blossoming figure in a low-cut leopard print clingy dress, which displayed plenty of her ample cleavage and clung to her tiny baby bump.
'Apparently it was a part of God's plan for my life,' she laughed as she chatted about her new pregnancy. 'I was extremely shocked because I was going through a lot of hormonal changes, trying to get back to the old, vibrant Jessica. You know, it was kind of like a one-night stand. And it happened, all over again!'
The glowing star is watching what she eats this time around, after gaining what she said was 'a lot more than doctors would recommend.'
Jessica admitted: 'I was really happy to be pregnant and I didn't ever step on the scale. I didn't realise you could gain that much weight that quickly.'
She added: 'I didn't really make any healthy good decisions.'
The singer and actress, who recently lost 50lbs on Weight Watchers, paired her racy ensemble with sky-high black satin heels and her platinum blonde hair was perfectly coiffed.
After waving to the crowd upon her entrance onstage, Jessica was animated as she spoke to Leno.

It was recently revealed that Jessica is already plotting her return to the small screen in a new sitcom pilot for NBC, which will be inspired by her life, and the blonde was happy to divulged about it.
When asked if it was about 'a girl who keeps getting pregnant', Jessica replied: 'Yes, and how that girl deals with that and everything else. I will be playing myself, which is pretty easy.'
She went on: 'We don't have a name yet, we're just now in the process of casting everyone, doing the pilot. I will be playing myself but we'll have actors playing Eric and my dad. That'll be funny.'
According to Deadline, the engaged star is excited to produce and star in the single-camera, half-hour series.
'I often find myself thinking that no one could ever make up the things that actually happen in my life — so between the real-life elements and a great team of writers, I think we’ll have people laughing!' Simpson said.
Executive producers for the pilot are already dubbing Jessica a 'modern day Lucy' - including Nick Bakay, Ben Silverman, Jimmy Fox, and Jessica’s father/manager Joe Simpson.
Silverman explained: 'From running a fashion empire to wrangling her public image as a new mom, we see Jessica’s character approach a variety of "everyday" circumstances that will get audiences laughing out loud.'
As many will know, this isn't the first time Jessica has dabbled in reality.
She became famous after starring with her ex-husband Nick Lachey in their MTV reality series Newlyweds: Nick and Jessica in 2003.
The Dukes Of Hazzard actress has also starred in her own docuseries called The Price of Beauty as well as appearing in little sister Ashlee's reality show.
Back in 2004, Jessica filmed a pilot called Jessica where she played a pop star-turned-TV news anchor, but ABC opted not to pick the series up.
Meanwhile, the Weight Watchers spokesperson and her fiancé Eric Johnson have been holidaying with their eight-month-old daughter Maxwell in Hawaii.
The Fashion Star mentor admitted she feels 'awful' when her work limits the amount of time she can spend with her daughter.
'Motherhood is the best thing I've ever experienced - and the most challenging,' Simpson told People magazine.
'On some of the days of Fashion Star, I'm awake before Maxwell is awake, and I'm not home until she's already back to sleep. That's only happened about four times, but it makes the day awful.'
She continued, 'I definitely need to see my baby. I get really sad if I don't get to see her. And then when Maxwell sees me, she just stares at me and touches my face. I can tell she missed me. That breaks my heart.'
