Mariah Carey And Nick Cannon's Baby News, A 'Community' Halloween Ep In Today's Tweet Dreams

Mariah CareyAfter tons of speculation from the media, Mariah Carey and hubby Nick Cannon have finally announced they are expecting their first child together. While the pair opened up to "The Today Show" and "Access Hollywood" about their expanding brood, they remained pretty mum about the whole thing on Twitter. Mariah (pictured) only reminded fans about her interview, "Tune in to Access Hollywood tonight for the 1st of Billy Bush's exclusive 3-part interview with Mariah. Get info @" But, that didn't stop other celebs from taking to their Twitter to leave their well wishes for the pair, including Ryan Seacrest who wrote, "Congrats to @MariahCarey & @NickCannon who've confirmed that she's pregnant!"

As Nick and Mariah prep for a baby, the cast of "Community" is getting ready for their big Halloween episode tonight. Actor Joel McHale joked yesterday, "Still in the market for a Halloween costume. Anybody know of a Big & Tall shop that has a Pikachu outfit in stock?" while his co-star Alison Brie was all dressed up and ready to go, sharing with fans, "Spooooooky Halloween episode of #NBCCommunity tonight at a special time *8:30/7:30c*!!!! Get ready..."
