Kim Kardashian tweeted for the first time Thursday since the birth to her baby girl North West.

The 32-year-old reality star has been silent from social media in light of her newborn, but nearly two weeks after delivering North, she tweeted special Happy Birthday wishes to her younger sister, Khloe Kardashian. 

"Then- @khloekardashian The birthday girl! I love you so much!!!!," Kim wrote on June 27. 

"In another tweet, she messaged: "Now- @khloekardashian The most loyal & supportive person on the planet! Life wouldn't be the same..." she wrote, along with a picture she posted of the sisters. 

Khloe, 29, has indeed been supportive of Kim. The former X-Factor judge was one of the first members of the Kardashian family who confirmed the birth of North West and expressed her excitement for Kim and Kanye. 

"I can not even begin 2describe the miracle that is now a part of our family. Mommy/baby are healthy &resting. We appreciate all of the love," she tweeted on June 16. "More info will come when the time is right! Thank you all for understanding! We love you all dearly! Overwhelmed with love right now."

Kanye also came out of hiding since the birth of baby North. The rapper was spotted walking around, attempting to hide his appearnce with a hoody, was joined by Kris Jenner in Los Angeles on Thursday. TMZ has obtained a video of the rapper telling photographers not to talk to him. 

Meanwhile, Kim is said to be adjusting to her new motherhood duties just fine, according to sources. 

After a few days home with North, who was born five weeks early and weighted just under five pounds, Kim seems to have a "natural" maternal instinct. 

When I walked in to see her, Kim was holding the baby," Kim's friend and Pussycat Dolls founder Robin Antin said. "I said, 'Oh, my God. You're a natural.' Kim said, 'I know -- it's so weird!'"

While fans were shocked that Kim and Kanye named their daughter, North, sources said the name has a significant meaning. 

"North is the most high. There is nothing higher than North," the source said. "And, when it comes to the stars, the sun rises in the East and sets in the West."
