BREAKING: Kim Kardashian IS pregnant with her second child

It's official: Kim Kardashian is pregnant.

The 34-year-old reality TV star and her rapper superstar husband, Kanye West, 37, already have one child, North, who will celebrate her second birthday on June 15.

This morning, and as the most recent episode of Keeping Up With The Kardashians was airing in the US, E! took to Twitter to confirm the happy news.

A teaser for a forthcoming episode of their hugely successful reality TV show had just minutes previously shown Kim turning to her sister Khloe and declaring: "I just got the blood test back, and I am pregnant!" 

Saying that she couldn't wait to meet the "new little love bug," momager Kris Jenner also this morning took to social media to express her joy at the impending arrival of another grandchild.

Kim and Kanye's struggles to conceive a second baby have been well-documented in recent months.

Us Weekly reported just this week that she was undergoing IVF and the latest screening of KUWTK furthermore saw Ms Kardashian visit a specialist doctor to discuss frankly her fertility. 

Kim even enlisted the services of psychic John Edward, hoping he could shed light on her difficulties. 

"You can’t psychologically dwell on conception and fertility," he told her. "What you need to do is visualise walking with a child. You need to see your daughter playing with a child.

"Astrologically it’s got to be the right time for that child to come in."

And last month, the California-native shared with E! news: "We are trying. We try every single day. You can't try harder than we try.

"It's getting exhausting. He always says: 'Trying for baby No. 2 isn't as fun as trying to baby No. 1.'''

It is not yet know when the baby is due. However, it is likely that the couple, who recently celebrated their one-year wedding anniversary, waited until the 12-week mark before announcing it publicly.

This means that the child will arrive at some stage in December. 

Kim's elder sister, Kourtney, 36, already has three children with her long-term partner, Scott Disick: Mason, five, Penelope, two, and Reign, six months.

In an interview with Elle late last year, Mrs West joked about the weight she gained while expecting North.

"I'd think God was doing this for a reason," she laughed. "He was saying: 'Kim, you think you're so hot, but look what I can do to you.'

"My body just went crazy," she added. "After five months I swore I'd never get pregnant again. I got so huge!"

North was born five weeks early and she has also described the pregnancy in subsequent interviews as "difficult".
