The couple began dating in 2009 and the Love Actually star exchanged vows with MCManus earlier this month (Sep12) in the picturesque Lake Como area in Lombardy, Italy - where George Clooney has a holiday home.
Rosie Nixon, editor of the U.K.'s Hello! magazine, broke the news of the nuptials on her Twitter.com page on Wednesday (19Sep12), days before photos from the pair's wedding will be published in the tabloid.
She writes, "I'm thrilled to reveal gorgeous couple @martineofficial & @jackmcmanus are now married! Their stunning Lake Como day is in Mon's @hellomag!".
MCCutcheon, 36, was previously engaged to DJ Gareth Cooke, but the relationship ended in 1996.
