Watch the adorable video of The Saturdays singer and the England rugby star tying the knot in front of their celebrity pals.
The four-minute video opens with Ben pushing Una on a swing before going to show scenes from the church and from the reception at Kilshane House.
Una has her hair and make-up done before her big day, The Saturdays are the bridesmaids, and then four-month-old baby Aiofe Belle features throughout.
'Best Day of My Life X,' tweeted Una, who shared the video.
