Natalie Portman and Pink's Baby Bumps; Jillian Michaels to Adopt (Photo Links)

As the baby boom of 2011 continues, pregnant celebrities Natalie Portman and Pink are showing off growing baby bumps, while America's Toughest Trainer Jillian Michaels is working on adopting a baby of her own.

Natalie Portman is truly starting to show and at the 83^rd Academy Awards Nominations Luncheon held yesterday (February 7) in Beverly Hills, the teal Lanvin dress with a sash really accented the growing baby.

Portman also donned pink shoes by Charles (Charles David), and carried a Christian Dior clutch.

Natalie is up for Best Actress for her role in Black Swan.

And then there is Pink who took a very casual self-photo of her own growing baby bump after feeling less-than-satisfied with the paparazzi's efforts to photograph her.

In fact, Pink tweeted on February 4^th the following: ""ALRIGHT... because paparazzi of today have absolutely no photographic skill or artistry whatsoever, and their pictures are hideous... I'm going to post a self-portrait I took yesterday morning for all of you asking to see belly shots."

Finally, there is America's Toughest Trainer Jillian Michaels who first gained fame for her role on The Biggest Loser.

Michaels, 36, is currently waiting on a phone call after completing all the necessary paperwork, physicals, background checks, etc. needed to be done in order to be cleared for adoption.

Michaels told Access Hollywood that she is ready to start a family and announced in December that she is leaving The Biggest Loser to focus on the adoption process.

Said Michaels, "That could be anywhere from six months to a year. I'm in a pilot program for the Democratic Republic of Congo so we'll see. Then you get your referral and then you have to try to bring your kid back home."

Congratulations to all three celebrities!
