Kim changes her last name on Instagram and Twitter

It’s like officially official, you guys… Kim has gone West.

Proving that social media has more power than any kind of legitimate marriage certificate, Kim K fans have gone nuts after spotting the reality star’s latest moniker on Instagram and Twitter.

Kim Kardashian West (not hyphenated, cause that’s tacky) took time away from her Irish honeymoon with new hubby Kanye West to update her (marital) status, telling bajillions of followers exactly what they already knew.

It shouldn’t come as a massive surprise, at her Vegas birthday in October last year the 33-year-old told E! “Yeah, I will. It’ll be Kim Kardashian West. No, not hyphened. Make it the middle.”

Meanwhile, Lana Del Rey has shot down rumours that she was paid millions of dollars to perform at the couple’s lavish European wedding.

“I would never let a friend pay me to sing at a wedding, that’s crazy,” she told TMZ.

Arriving back at LAX, she was swarmed by fans and paparazzi all wanting the goss on the Kimye nuptials, check it out in the video below.
