Introducing Mrs. Kim Kardashian West: E! Star Adds Kanye West's Surname to ...

Welcome to Twitter and Instagram, Mrs. Kim Kardashian West!

Well, technically, the E! star was already active on both social media sites, although she has now added Kanye West's surname to her profile pages.

The two tied the knot in a lavish ceremony, surrounded by approximately 200 of their closest family and friends on Saturday, and it looks like Kim just couldn't wait to take her man's last name, as the newlywed continues to post pics from the duo's special day with the caption, 'Mr. and Mrs. West.'

In October, the 33-year-old beauty told E! News that she planned to take Yeezy's surname after the gorgeous couple made it official.

'I will,' North West's mama told E!'s Ken Baker on the red carpet of her Las Vegas birthday bash at Tao when asked if she will take Kanye's last name, adding that she will not hyphenate her moniker and will instead make Kardashian her middle name.

Kim and Kanye are currently enjoying a romantic and top-secret honeymoon in Ireland, as Nori spends some extra time with grandma Kris Jenner. E! News has learned that the lovebirds spent time at the Castle Oliver in the south part of County Limerick.

The couple's ceremony on Saturday at the historic Forte di Belvedere in Florence, Italy, was nothing short of spectacular. Kim looked stunning in a one-of-a-kind Givenchy Haute Couture gown, while her man was fitted in a custom Givenchy tux.

And of course baby North West was also present for the ceremony, wearing a custom haute couture Givenchy dress, which matched her own bridal mama's beautiful number.

Following the ceremony, the couple enjoyed a lavish reception, during which Kris Jenner made a 'big emotional' speech that sources tell E! News was a tribute to Kim, Kanye, and their daughter. And of course, 'Ye also took the podium, giving a 20-minute speech which paid tribute to his new wife and the Kardashian family, whom he called 'the most remarkable people of our time.'

Celebrity guest John Legend also serended the couple with his hit tune 'All of Me,' before the pair enjoyed their first dance to an mashup.
