Since news broke that Kim Kardashian is expecting her first child with Kanye West, the reality TV maven has been consistently been spotted at the gym, suggesting that she wants to have a healthy, active pregnancy.
Now, Kim herself has confirmed the theory, revealing that fitness guru Tracy Anderson is the woman she has charged with keeping her famous curves toned over the next nine months. "Tracy Anderson is keeping me in shape," the star wrote on her blog.
"She is helping me make the adjustments necessary to keep me feeling happy, healthy and most importantly create a workout plan that is safe for the baby. It's really important for me to have a fitness routine that works for my body and my schedule and I'm really happy with the workout plan Tracy is working with me on."
Kim is certainly in good hands. Tracy is the celebrity trainer whose challenging regime is responsible for Gwyneth Paltrow's sylph-like red carpet silhouette. Having got into shape for Iron Man 2, the Hollywood beauty credited Tracy's pilates style workouts with allowing her to "do ridiculous things like be a 37-year-old mother of two and wear shorts".
The trainer recently welcomed baby daughter Penelope with her husband Matt Mogol and launched a pregnancy fitness regime, so no-one is better placed to advise Kim, whose baby is due in late 2013.
Her beau Kanye West confirmed the happy news during a New Year's Eve concert. With his girlfriend watching from the audience, he said "stop the music", before asking the crowd to congratulate his "baby mama". "Make noise for my baby mama right here," he said with a smile from ear to ear.
The Kardashian family were quick to tweet about their excitement and share their feelings on the happy news. A clearly delighted Kourtney Kardashian tweeted: "Been wanting to shout from the rooftops with joy and now I can! Another angel to welcome to our family. Overwhelmed with excitement!".
Kim's other sister Khloe, who appears to be relieved that the pregnancy is out in the open, wrote: "Keeping secrets is hard with so many family members! Especially when you are so freaking excited!!!!! LOVE is everything!!!!".
Her husband Lamar Odom, meanwhile, joined the well-wishers by tweeting: "I'm excited for Kanye and my sister! There's nothing like bringing life into this world! Let's keep God's blessings coming!".
