It sounds like Fergie, who is currently pregnant with her first child with husband Josh Duhamel, is getting some hands-on parenting lessons from the hilarious Fashion Police host Joan Rivers.

“Taping 4 tmrw's #FashionPolice. Breast feeding class w/ #joan_rivers,” wrote Fergie, with this hilarious picture of the Black Eyed Peas singer sitting on Rivers’ lap, who is pretending to breastfeed.

Fergie was on the show to talk about pregnancy fashion. “Rocking my maternity #style w/ @FergieFootwear, TONIGHT on #FashionPolice!” she later wrote, with a picture of her on-set at the show.

“Happy Mother's Day to my wonderful mommy Terri & all the strong mamas out there,” tweeted Fergie.

“Don’t tell my mom, but I made her a @CaseMate w/ this pic of me 4 #MothersDay. Honor yr mom,” she wrote, with a link to this photo of an iPhone case with a picture of her as a child. Love it!

Sugarland singer Jennifer Nettles shared this first photo of her son, 5-month-old Magnus Hamilton Miller, on Mother’s Day.

“So much love and joy on my first Mother's Day! A very Happy Mother's Day to all the Mamas!’ she tweeted, with this photo of her lying down and cuddling with her adorable baby boy.

“Family-ville is super sweet (but I do miss y'all too!!),” Nettles tweeted.

While the singer is home with her baby, it sounds like she is getting caught up on the joys of daytime TV! “Lots of writing and lots of baby. Both are so fun! Also, some important things I've learned from daytime tv: 1. We all need to change our money into gold & 2. Never get a vaginal mesh,” she joked.

Nettles is adjusting to breastfeeding — and learning the important new mom skill of multitasking.

 “New tshirt idea for nursing moms. The front says 'The Breastaurant.' The back says 'Bon Appe-tittie.' #talkamongstyourselves,” she wrote. “Thing [I] never thought I'd know: in winter, nipple cream can also serve as a great moisturizer for dry hands. #multi-tasker.”

Kourtney Kardashian

“Back in the day when I was young. I'm not a kid anymore,” Kourtney Kardashian tweeted, with this photo of her and her sister Kim Kardashian as kids with their mom Kris Jenner, who looks a lot like Kourtney in this picture!

“A beautiful Mother's Day,” wrote Kourtney, who has two kids (Mason and Penelope) with her boyfriend Scott Disick.

“Happy Mother’s Day to my fabulous mother who has taught me so much about being a mother myself,” she wrote on her website. “I respect the love, enthusiasm and effort that you have put into all of us. I love you beyond words. I feel so blessed to have my mother and grandmother to look up to every single day.”

“Sharing fashion moments with mom!” she later tweeted, with a link to a photo of Kourtney with her mom and sisters.

“My sisters and I recently sat down with People magazine to talk about some fun fashion memories of our mom,“ she wrote. “My mom’s style has always been so inspiring to me, and it was fun to reminisce with my sisters about our days of rummaging through her closet! When I was a little girl, I would always play in her closet with Kim. She put the love of fashion in our blood. I have always admired her style and still do. She has an effortless style… and an eclectic style.“

Snooki and son LorenzoSnooki

“Chillen with the love of my life,” tweeted Snooki, with a photo of her son Lorenzo.

“With some of my girls celebrating my first Mother's Day!!” tweeted Snooki, with a link to a photo of her and some friends.

“I'm sorry but I just have to comment on some of the ignorant comments I read on my pictures,” tweeted later Snooki, with a link to a comment made on her instagram photo that said: 

“I love you snooks but Mother’s Day is about spending time with your children, your pride and joy. Not an excuse to go out and party. Kind of sad you haven’t realized that by now,” wrote one commenter on Snooki’s instagram picture.

 “First of all its none of your business to even tell me how to spend my Mother's Day,” wrote Snooki. “Secondly, I'm not partying. I spend every waking minute with my son and couldn't be any happier. I sent jionni to the players championship this week for his birthday, and spending my Mother's Day with my son, mother, grandmother and friends. You don't personally know me to be so rude and ignorant. I can't stand people making rude accusations about me being a mother. Show some respect. That is all.”
