The Twilight star was at the bar in his Belfast hotel in Northern Ireland when he was spotted by bridesmaids and approached on Saturday (29Aug15).

Attendee Jamie Reid says, ''I plucked up the courage and went over and said he was going to get mobbed by about 20 girls. He is such a quiet guy and he was a bit taken back by it, all these girls.''

Pattinson posed for pictures with the bride and groom and members of the wedding party, before hotel security stepped in and escorted him back to his room.

Reid continues, ''In fairness, he sat and got his pictures taken until the Culloden staff came and moved him on.''

The 29 year old is currently in the country filming his new movie The Lost City of Z.
