Hollywood's most ridiculously good-looking couple - aka Alicia Vikander and Michael Fassbender - have reportedly tied the knot during a low-key ceremony in Ibiza.

The private stars - who have been in a relationship for three years - were pictured wearing matching silver bands on their wedding fingers, not long after reports last month that they were planning to marry in Ibiza in October.

The Sun reported that Fassbender was planning on paying for their friends and family to stay in a five-star resort ahead of their big day, with a source adding to the newspaper: 'The details of the party are being kept under lock and key.

'Guests have been told to arrive in Ibiza on a certain date and they will then be collected and taken to the hotel. He's splashing out big time and it's going to be the party of the year.'

The happy-looking pair were also photographed drinking and celebrating with guests - including director Steve McQueen - and being congratulated with hugs during a reported post-wedding lunch at a beach restaurant.

Fassbender was wearing a short-sleeved Hawaiian shirt over a white vest and a pair of navy shorts, while the Oscar-winning actress wore a pale blue floral smock.

Since meeting on the set of 2014's period drama The Light Between Oceans, the couple have preferred to keep their relationship out of the spotlight.

'I think we've made a clear statement that we keep certain things just between us,' the Danish star told Entertainment Weekly.

'It was very easy to unite, but that's quite personal.'

Meanwhile, the Shame actor added: 'I'm not going to talk about my private life with a total stranger, unless I feel like I need to. Why would I? I don't.'

Representatives for the couple have yet to confirm their engagement and reported nuptials.
