Wearing a hat and flashing her signature smile, mom-to-be Jessica Simpson steps out with her stylish sis Ashlee Simpson to promote the pair’s new line for tweens, Jessica Simpson Girls, on Saturday at The Bay in Toronto, Canada.

Joining the pair? Bronx Mowgli, 3, Ashlee’s son with ex-husband Pete Wentz.

So will Jessica, 31, and fiancé Eric Johnson find out the sex of their baby, or wait for a surprise?

“I don’t think we can wait. Jessica is too honest about everything, she needs to know,” Johnson laughingly tells PEOPLE.

I think Jessica looks so pretty. I think Ashley is pretty but I really don’t like her hairstyle.

Ashlee is really pretty but she could choose better clothes. Jessica on other hand is very stylish

Jessica looks lovely… if she hasn’t found out the baby’s sex yet, does that mean she is not even quite 5 months pregnant? If so, she must be carrying quite large… she is the same size as me and I’m nearly 30 weeks pregnant with my 3rd child!

Ashlee and Jessica both look great. I love Ashlee’s style – she’s always unique and doesn’t care what people think about her. =) Bronx looks alittle like Daddy (Pete) in the face but def takes after Mommy a lot. Exp with the blonde hair. Guessing the curls came from Pete’s side though. =)

Violette- It could very well be that they’ve TRIED to find on the sex…but the baby hasn’t cooperated!

Bronx looks like daddy, but he has Ashlee’s eyes. I can’t wait for Jess’ child to be born – I love her!
