Justin Bieber and Hailey Baldwin had their wedding rehearsal in South Carolina last night

The countdown is on.

Mr and Mrs Bieber are getting ready to throw one of the most anticipated celeb weddings of the year as they walk up the aisle surrounded by their friends and family. On Sunday night, the pair threw a pre-wedding dress rehearsal at the lavish Moreland Landing near their 5-star hotel. Travelling to the venue in small boats decked out with red hearts, the Biebers' wedding party of 36 guests partied the night away as they celebrated the happy couple. For the occasion, Hailey wore a short white off the shoulder mini dress and Jimmy Choo strappy heels, decked out with two large bows on the back of them. Justin, on the other hand, who is forever changing his look, appeared clean shaven with his hair cut. He wore a polo and black trousers. Justin and Hailey will reaffirm their vows in a religious ceremony this week having had a courthouse wedding last year. In attendance at the wedding will be Hailey and Justin's families as well as celebrity friends like Katy Perry and Kendall Jenner who boarded a plane for South Carolina yesterday. The ceremony will take place at the hotel's larger chapel - seating 185 people.

A source told the Daily Mail that the reception will take place at sunset, with a reception to follow in the hotel's ballroom – a short walk from the chapel.

The ballroom for the afters has also been decked out by events company Revelry Event Designers - the people who also supply décor for the Oscars and the Grammys.

Now, we're buzzing to see all the glitz and glamour from the big day, let alone Hailey's bound to be amazing dress.
