Snooki wants her and Jwoww to conceive on the same night.

The reality TV stars - who have a 'Jersey Shore' spin off named after them - are both busy planning their weddings to Jionni LaValle and Roger Matthews respectively, and Snooki - real name Nicole Polizzi - is hoping they both fall pregnant together too.

Jwoww - real name Jennifer Farley - told In Touch Weekly: ''We want our weddings close together, I'd love to have mine in September then Nicole could do November.''

Snooki added: ''I'll probably get pregnant on my wedding night, that's the goal. We should get pregnant together, can we please try and conceive at the same time? We already ovulate at the same time.''

Snooki - who already has son Lorenzo, 16 months, with Jionni - says she'd love for the to have children of different sexes, so they could date.

She added: ''I need to have a girl and you have a boy and then they can date. We'd be in-laws! Can you imagine us spending Christmas together when we're 50? It would be awesome.''
