His previous relationship with Twilight co-star Kristen Stewart was very much conducted under the spotlight – so understandably Robert Pattinson, 29, is seriously guarded when it comes to his private life now.

Indeed, his proposal of marriage to new love FKA Twigs was only confirmed in April – when rapper T Pain leaked the news inadvertently. 

So – unlikely as it seems – when the musician shared a snap of a stunning white, beaded and lace dress on her Instagram account last night, fan theories went into overdrive – with some even suggesting that the stars' wedding was taking place today.

Others reckoned the Big Day had already taken place, with FKA Twigs – real name Tahliah Debrett Barnett – posting the photo to confirm the happy news.

"Omg! Wedding dress!?" said one. "Could she be trying on her wedding dress?" suggested another. "Omg they married?" asked a third.

However, it transpires the 27-year-old English singer was simply… getting her hair cut.

Say what?!

Yes, while showing off the dress – which does look remarkably bridal – she wrote: "Inches and scissors never hurt anybody," and on closer inspection, she is indeed sporting shorter tresses.

Earlier this month, Robert and his mum were seen at one of FKA Twigs's gigs in Manchester.

The couple has so far refused to even hint as to when their nuptials might take place – meaning fans will have to continue speculating for a while yet.

And whenever the happy couple does indeed tie the knot, we can be assured that fashionista Twigs's dress (if we ever get to see it!) is going to be spectacular.
