The first 24 hours of Nikki Reed and Paul McDonald's married life seem to be going quite well. The newlyweds took to Twitter to let their fans know just how happy they are after Sunday's wedding.

"Yesterday was the most magical day of my life..." the "Twilight" actress tweeted Monday (October 17), one day after she said "I do" to the "American Idol" singer.

"Yesterday was the most amazing day of my life," Mc Donald wrote, echoing his bride's enthusiasm. "Everything was perfect. I'm officially a MARRIED MAN! Woohoo!"

The couple married in front of 100 guests in Malibu on Sunday. E! News reports that "Idol" singer Stefano Langone played the reception, along with McDonald's band, Grand Magnolias. McDonald also reportedly performed at the party. "Spy Kids" star and Reed pal Alexa Vega served as a bridesmaid at the festivities.

"We couldn't be happier!" the couple said in a statement after news broke of their wedding. "[We were] surrounded by our family and friends. We're so glad this day has come!"

The two began dating in April and got engaged just two months later. They announced their plans to marry at the MTV Movie Awards in June, where Reed was spotted sporting an engagement ring.

"She's amazing. It's kind of one of those things you don't expect," McDonald gushed to MTV News earlier this year. "Like, last year I never would have thought I'd be getting married. She's amazing. She's the perfect girl. We fit each other. When you know, you know, and she's the one."

The pair have been quite public about their relationship. McDonald plans to release an album tentatively called The Nikki Reed EP, and when Reed hit up the Teen Choice Awards in August, she was sporting Paul's face on her nails and revealed that he was being quite the bridezilla.

"He's doing a lot of it, he is. He's, like, taking control," Reed said about McDonald's part in the wedding planning. "He sits with his computer in between songs and is kind of on a roll with everything."
