Lady Gaga

Health issues have forced Lady Gaga to cancel her concert at Purdue University last night. The problems seem to be due to a mystery illness, the school representative declared. According to TMZ.com, Purdue EMTs showed up at the Elliott Hall of Music to attend to Gaga, but the singer's people turned them away. It turns out that Gaga just boarded her tour bus and left campus.

No statement has been made by Gaga's spokesperson.
The concert has been rescheduled to January 26.

Elton John

Sir Elton John had to postpone some of his concerts due to one illness. The singer wrote on his website that his concerts scheduled for November 4 and November 7 in Seattle, and November 10 in Portland would be postponed because the singer had been "advised by his doctor to postpone these performances due to a serious case of e-coli bacterial infection and influenza", The Insider reports.  The words 62 years old singer used to describe his situation was showing that he "continues to be unwell and is unable to perform." It seems that that people who already bought tickets are asked to keep them since the organizers are trying to reschedule the concerts.

Natalie Cole

After she suffered a kidney transplant, Natalie Cole has returned to the concert stage for first time. It happened Wednesday night at the Hollywood Bowl in Los Angeles. The 59 years old singer suffered the surgery in May this year.
At the concert she wore a purple jewel-studded gown by designer Lloyd Klein as she was receiving standing ovation from the public.
Natalie sang songs from her latest album, 'Still Unforgettable' and also songs from her Grammy-winning career.

Madonna

Is Madonna too old to sustain a world tour or she just overreacted with her vegetarian diet? We don't know yet, but one thing is for sure: the singer collapsed on stage during her final Sticky & Sweet concert in Sofia, Bulgaria. According to The Sun, Madonna refused to end the show and continued after visibly feeling weird during the Holiday song.  She took a break off stage during Spanish Lesson after falling sick again."Madonna was really worried backstage. She had to sit down for a longer break than usual between songs. She refused to end the show after the Holiday dizzy spell. It turns out she is suffering from exhaustion. She is anemic", a source declared for The Sun.
It seems that close people have advised Madonna that she was too tired for the last two shows, but she didn't listen. "She was advised to postpone the last two shows for a few days, but logistics and stubbornness stopped her. She'll do them and then take a rest", the source added.
