Identical twin sisters want to marry 'shared' boyfriend, but can't

Reason? Polygamy is forbidden in Australia.

The 33-year-old sisters have been dating Ben Byrne since 2012, and want to marry him.

They recently appeared on Hughsey, We Have A Problem, where the host Dave Hughes solves the problems of viewers, guests and panel members.

However, he wasn't able to find a solution to this problem, although the show members found the problem pretty amusing.

"If we can change the law and the government, we'd love to marry Ben. I mean love is love," Anna said.

Interestingly, when questioned if it was possible for them to get pregnant together, Lucy said "it'd be amazing."

However, after the initial excitement, the sisters got confused and pointed out, since the kids would share the same father, what would their relationship be?

'People would be saying "would they be cousins?" Would they look the same? They would be related hey? I find this fascinating," they said.

However they were quick to note, "There's a lot of pressure on Ben, but it's all up to him."

The sisters are also mulling going for surrogacy, IVF or adoption, if they fail to conceive the natural way.

The siblings, fashion bloggers by profession, spent nearly $250,000 (Rs. 1.75cr) on cosmetic surgery to become 'world's most-identical twins'.

In their 20s, the sisters opted for years of lip fillers, breast implants, facial tattooing, skin-needling, laser treatments, and even eyebrows and hair extensions.

But they later realized that they overdid the procedures, and removed eyebrows and lip tattoos and also let their fillers dissolve.
