A new storyline, which has already kicked off in Australia, sees the pair planning to tie the knot in a desperate bid to impress Vanessa's overbearing mother Francesca.
However, with Vanessa's ex-boyfriend Rhys Lawson also attending the big day, it seems that one of the year's most complicated love triangles will finally be resolved - or will it?

A Neighbours statement teased: "True to form for this volatile threesome, these are not your traditional nuptials with two prospective grooms vying for the bride's hand.
"The wedding was filmed in an historic chapel in July - the perfect backdrop for the romantic event complete with all the trimmings. While producers are tight-lipped on the outcome, we can reveal fans will be left reeling with a surprise twist."
Alin Sumarwata, who plays Vanessa, added: "Vanessa is a thrill seeker. Running from the truth is hard enough but doing it at a staged wedding, eight months pregnant, in stilettos no less, isn't for everyone. I wouldn't recommend it!"
Neighbours airs the wedding scenes on November 13 in Australia and December 11 on Channel 5 in the UK.
