Katy Perry dishes on her relationship with Orlando Bloom's ex wife Miranda Kerr

The 'Roar' songstress and Kerr spoke on Instagram Live Tuesday about their blended family. "One of the great things about being close to Miranda is I get to try out all her products, especially when her son [Flynn] comes home with them in his backpack," Perry said while helping Kerr promote her KORA Organics skincare line. 

The 37-year-old model said, "The kids are my number one love. It is just the best thing in the world, being a mom." Perry agreed, "It is the best job. It is the most fulfilling. There was no feeling like the feeling when I had my daughter. That was like all the love I was ever searching for, like, bam!" 

During the virtual conversation between the two, the 'Dark Horse' songstress described how she used to feel fulfilled in her career by performing but says motherhood has changed her perspective on life. "The love from your children is constant and unconditional and isn't based on what you have, what you do not have, what career, what product and that's definitely made me feel so full to know that there's this unwavering and unconditional love," she described. 

Perry continued, "I am so glad I made the conscious decision to actually try and do that because I did not want to miss out on that opportunity... It has been the best thing." Kerr also shares sons 2-year-old Hart and 1-year-old son Myles with her husband, Snap Inc. CEO Evan Spiegel. 

As reported by Fox News, back in November, the former Victoria's Secret model told Drew Barrymore that she adores Perry. "I adore Katy and I just feel so happy that Orlando has found someone that makes his heart so happy, because at the end of the day, for Flynn to have a happy father and a happy mother is just the most important thing," she gushed. "I am just so grateful that Orlando and Katy found each other and I am so grateful that I found my incredible husband and just that we all really respect each other." 

Kerr also touched on co-parenting with Bloom. "We work it out so we have compromises [about] what is the best for our whole family," she said, adding, "We really do always think of what is the best thing for Flynn, and I just think that's the most important thing.
