Pink took to Twitter to defend her parenting skills, after her husband Carey Hart took Willow on a motorcycle ride.

Pregnant Kristin Cavallari and CamdenKristin Cavallari

Kristin Cavallari is pregnant again! The Laguna Beach alum and her boyfriend, Chicago Bears quarterback Jay Cutler, are expecting their second child together. They already have a 14-month-old son, Camden.

“Thank you for all the love!! We are so excited for Camden to be a big brother!” she tweeted.

Even though she had previously said she would “love to have a little girl,” she quickly took to Twitter to clear up rumors that they already knew the sex, a rumor that Heidi Montag had apparently started!

“Lol...@heidimontag jumped the gun...we don't know the sex,” she wrote.

Cutler sustained a serious groin injury in October, and fellow football wife, Kim Zolciak, reached out to Cavallari. "Praying for a speedy recovery for your Hubby @KristinCav sucks having them injured," tweeted Zolciak, who is pregnant with twins and due this December.

"Thank u @Kimzolciak we wish your hubby the best too,” Cavallari replied.

Katie Holmes

Katie Holmes has finally joined Twitter, using the handle @KatieHolmes212. The actress sent out her first tweet on Oct. 25 and already has over 40,000 followers, with her profile simply stating “actress.”

She is currently following 18 people, and that short list doesn’t include her ex-husband and father of her daughter Suri, Tom Cruise.

She dipped her foot into social media by re-tweeting this cast photo from producer Nikki Silver, who wrote, “loving South Africa” as she shared a photo from The Giver movie, which included Taylor Swift and Jeff Bridges.

Pregnant Melissa Rycroft baby bumpMelissa Rycroft

“Good morning little baby bump,” tweeted Bachelor alum Melissa Rycroft, who recently announced she is pregnant with her second child. “Well...still kinda looks like I ate a little too much, but still such a sweet sight!”

Rycroft shared this selfie as she lifted up her shirt to reveal her little baby bump. The Dancing with the Stars alum announced her pregnancy via Twitter, showing off her positive pregnancy test. She and her husband, Tye Strickland, already have a 2-year-old daughter named Ava.

“Fall Festival at school. Who says Sulley has to be a boy?!? When a girl sets her mind to something..,” wrote Rycroft, sharing a photo of Ava dressed as Monsters Inc.'s character Sulley.

“I told Ava we were going to the doctor today, and she asked if there would be a stethoscope (well...a stepospoke). What?! It amazes me the things she's aware of that I didn't even know she knew about,” she later wrote.


Pink's daughter Willow on motorcycle with Carey Hart

Singer Pink took to Twitter to defend her husband, Carey Hart, after he posted the following photos of him taking their 2-year-old daughter, Willow, for a motorcycle ride.

“Been waiting for this day for a very long time,” Hart captioned the photo. “Willz went for her 1st ride on my motorcycle around the pits today. She was pumped the whole time. When we stopped, she gave me a big hug and said it was fun, thank you Papa. That's my girl.”

Apparently, fans of Pink tweeted their disapproval over her letting her daughter ride on a motorcycle.

“If any of u have more experience on a bike than my husband, then I will listen to your opinions on how he should take my daughter for a ride,” tweeted Pink. “I can't promise I will care, but I will listen none the less.”

“Wait until she's 16 and let her decide for herself. Bikes are no joke!” one follower tweeted to Pink.

"Yeah ok. I've never met you but that's great," Pink replied.

"Honestly.. I wouldn't like the idea of a child so young being on a bike,” tweeted another follower.

"Then I don't recommend it for your child," the singer snapped back.

"M'kay I'm gonna go now," Pink wrote. ""Gotta figure out what wills is wearing tomorrow for her MANIACAL MOTO MANIA!!!!!! Gotta pack veggies too! Organic!"
