Beyonce Knowles is Kim Kardashian's inspiration as the reality TV star aims to lose her baby weight.
The 'Halo' hitmaker regained her pre-pregnancy figure in record time after giving birth to her daughter Blue Ivy in January 2012 and Kim - who recently welcomed daughter North with boyfriend Kanye West - hopes to follow in Beyonce's footsteps.
A source told Us Weekly: ''She won't leave the house until she's thinner, she can't lose the weight fast enough. And she's frustrated she can't exercise yet.
''She really looks up to Beyonce.''
Meanwhile, Kim, 32, who has maintained a low profile since giving birth on June 15, finally broken her silence this week to thank fans for giving her time to adjust to the special new addition in her life.
Addressing North's arrival for the first time on her official blog, the 'Keeping Up with the Kardashians' star wrote: ''These past couple of weeks have been filled with the most exciting experiences of my life. I'm enjoying this time to fully embrace motherhood and spend time at home with my family.''
She added: ''I've been reading all of your messages and want to thank you all for your sweet thoughts and best wishes. It truly means everything to me. I am so blessed to have the support of my family and fans in this beautiful moment.''
The ‘Luther’ actor is one of the hot favourites to take over from Daniel Craig.
Perry made more than any other musician this year including rival Taylor Swift and boyband One Direction.
