Harry Styles and Una Healy certainly enjoyed Marvin and Rochelle’s wedding!

Looks like Harry Styles and Una Healy left Marvin and Rochelle's wedding a pair of very happy guests last night.

Harry and Una appear to have been taking FULL advantage of the free bar at the wedding which was held at Blenheim Palace in Oxfordshire.

Una had to literally cling to Harry's arm to keep herself steady.

Guess there could be worse places to cling.

In fact, we think every nightclub should start stocking Harry Styles' in the back room which they hand out before the dreaded walk to the night bus.

So yes, Una and Harry defo looked a little worse for wear at they arrived back at The Feathers hotel, which we revealed as the pre wedding venue yesterday.

However, do you blame them? It is their best mate's wedding and if you can't get drunk at that, when can you?

Plus, they look like they are having a right giggle and make us even more jealous that we must have missed our invite.

And new mum Una deserves a big night out after all that looking after Aoife!

The Saturday wore a black tracksuit, the same one she arrived in earlier in the day, we imagine to keep the bridesmaid's dresses top secret.

But who knows? Maybe Rochelle fancied a troop of trackie clad bridesmaids?

Harry's appearance also pretty much confirms yesterday's rumors that some of One Direction had checked into The Bear hotel in Woodstock, Oxfordshire.

We had doubted the rumours after Niall tweeted that he was in the studio.

However, Harry tweeted yesterday afternoon, 'It's been an eel-ly good day', which we know now must be a reference to the wedding.

Perhaps they had jellied eels on the wedding breakfast menu?!

Congratulations again to Rochelle and Marv!
