The Saturdays singer and the England rugby ace - who become parents to daughter Aoife Belle in March - tied the knot in a little church in Tipperary, Ireland, on 30.06.12.
Una`s bandmates Vanessa White, Mollie King, Rochelle Wiseman and Frankie Sandford were her bridesmaids while JLS were among the guests.
The day before the nuptials, Una went for a few drinks with her friends and posted a couple of pictures on her twitter account with the captions: "Having a last single drink with my old pal smarties!! X" and "All the single ladies!! (sic)"
Una, 30, had said last week she wanted the day to be as relaxed as possible, saying: "I want a nice, laid-back, fun day."
Rochelle - who is marrying JLS star Marvin Humes - and Una had a joint hen party in May with their bandmates, partying at London`s Rose Club.
The wedding took place just after Ben, 26, returned from England`s recent rugby tour of South Africa.
