Kim Kardashian, Kanye West Get Baby Love From Demi Lovato

While it might be a while until they need to call on a babysitter, it seems Kimye already have one eager and willing volunteer. Shortly after Kanye West announced that he and Kim Kardashian are expecting their first child together, Demi Lovato couldn't help but share her excitement with the world.

"So happy for you @KimKardashian.. Love you SO much and I'm so excited to babysit!!" she tweeted on Sunday night. "Miss you girly.. Once again... SO happy for you!!! Xox"

Lovato has been a longtime friend of the Kardashian family. She also happens to work with Kim's baby sis, Khloe, on "The X Factor," so it shouldn't be too hard for Kim and Kanye to hold Demi to that promise.

Demi is hardly their only famous pal sending the soon-to-be-parents some love. Russell Simmons tweeted, "Congrats to Kim and Kanye. Happy for both of them..."

Ryan Seacrest added, "It's true :) @KimKardashian & @KanyeWest are having a baby! congrats u guys"

"Kimmie's going to be a mommy!! Sending major love & congrats to @KimKardashian and @kanyewest!" Kim's friend, fellow reality TV star La La Vazquez Anthon! y tweeted. "2013 is starting off with LOVE and BLESSINGS!"

"The Office" star BJ Novak had some other good news for the couple, joking, "Congrats to Keeping Up With The Kardashians on your 18 season renewal."

Kanye announced that he and his lady love were expecting a bundle of joy Sunday night at his show in Atlantic City. It is reported Kim is approximately 12 weeks along, and Yeezy told the crowd at the Revel in AC to "make some noise" for his "baby mama."

For her part, Kim simply instagrammed a photo of her boo on stage with the caption, "Heaven."

The pregnancy was later confirmed by her sister, Khloe, who tweeted, "I'm excited for Kanye and my sister! There's nothing like bringing life into this world! Let's keep Gods blessings coming. "

Her momager, Kris Jenner, also couldn't contain her joy at the prospect of becoming a grandmother for the third time (daughter Kourtney has two children). "Im a happy girl! Wowza," Jenner tweeted. "Oh BABY BABY BABY!!"
