The Saturdays star married the JLS singer at Blenheim Palace in Oxford two weeks ago (July 27) in front of family, friends and several celebrity guests.
Rochelle Humes revealed that she cried throughout the ceremony, especially during their vows to each other.
"It just hit me, what we were saying to each other. It was all so overwhelming, I couldn't stop myself from crying," she told Hello!.
"I looked at Marvin and his eyes were glassy. I kept thinking he might go too, but he held it down."
Marvin Humes said that he was "desperate" to see his bride before the actual ceremony, but managed to wait until the big moment.
"When the music started up and I knew Rochelle had arrived, I was desperate to turn around and look at her," he said. "We hadn't spoken all day and had spent the previous night apart. I'd missed her and I couldn't wait to see her.
"But so many people had said to me that I shouldn't turn around - that it was unlucky.
"Then, when I looked to my left and she was there, oh man, she looked unbelievable; more beautiful than I've ever seen her look. Her face, her smile, the dress, everything... She was absolutely stunning."
The newlyweds have postponed their honeymoon by five months due to their busy work schedules.
Rochelle and Marvin Humes's full interview appears in Hello! magazine, which is out today (August 6).
