The television producer announced her new name via Twitter on Friday (21 August), as she thanked fans for their well wishes on the marriage.
"Hello, Twitter friends. It's officially @Storm_Keating now #MrandMrsKeating," she wrote. "A heartfelt thanx from my husband @ronanofficial & I for the beautiful messages & congratulations. Overwhelmed with all the kind words."
Ronan, meanwhile, has updated his Twitter bio to refer to his "wife". Aww.
The Boyzone star and his Australian producer partner married in Edinburgh on Monday, 17 August, holding the reception at the luxury Archerfield House. Guests in attendance included the Boyzone guys, Brian McFadden and Dannii Minogue.
They met in Australia when Ronan was working as a judge on the country's X Factor and Storm was a member of the production team. Ronan later proposed twice and Storm accepted both times!
This is Ronan's second marriage. His divorce from first wife Yvonne Connolly - who is the mother of his three children, Jack, Marie and Ali - was finalised earlier this year. He split with Yvonne in 2010 following his affair with a Boyzone backing dancer.
