Jessie J And Her Colorful Outfits Won’t Be Joining Katy Perry On Tour [PHOTOS]

Singer Jessie J has been partying it up in one colorful outfit after another. Jessie, wearing purple from head to toe, attended Jason Derulo’s launch party for his new album Future Hits at Merah in London last night. Today, she was spotted leaving her hotel in a bright orange coat to head to the VIP Room for a private concert.

Due to Jessie’s foot injury, a very disappointed Jessie, had to pull out of Katy Perry’s tour. The singer told MTV she was heartbroken:

“I was so honored for her to ask me to support her on the last leg of her amazing show. I saw it when I was in Australia. But sadly I went to see my doctor and he has advised me that if I do the diary – including the Katy Perry tour – that I won’t heal 110%. So unfortunately, as much as it breaks my heart to say it, I’ve had to pull out of the Katy Perry tour.”

Jessie has been replaced by pal Ellie Goulding, who she was spotted partying with last night at Jason Derulo’s birthday bash.

She added: ‘Health has to come first. I’m so sorry Katy. Please let us sing “I Kissed A Girl” dressed as cupcakes one day! You know what, as I’ve always said, everything happens for a reason.
