Madonna has hinted that she may be performing at the Grammy Awards on Sunday (January 26)

Writing on Instagram earlier this month, the singer said she was "looking for the perfect pair of heels to wear to the Grammys."

However the 55-year-old star was recently seen on crutches after bruising a "bone in her foot from dancing in high heels."

However it seems she has made a rapid recovery after posting a further image of herself smiling and revealing a golden grill.

"My lips are almost sealed! I can't say anything more. #itsasecret," the controversial singer wrote.

Los Angeles Times recently reported that an insider "with knowledge of the plans" claimed Madonna was going to join Beyoncé on stage at the LA's Staples Centre.

The R&B singer was recently heard raving about how the Material Girl has influenced her own career.

Beyonce has said that Madonna has been a huge influence on her career.

"I felt like I wanted to follow the footsteps of Madonna and be a powerhouse and have my own empire and show other women when you get to this point in your career you don't have to go sign with someone else and share your money and your success,' said Beyonce.

Power couple Beyoncé and rapper husband Jay Z are up for ten Grammy's at the awards.

A seven times Grammy winner Madonna has performed at the 2006 and 1999 Grammy Awards, and famously kissed Britney Spears and Christina Aguilera during a provocative stage performance.

It is also rumoured that the two surviving Beatles Paul McCartney and Ringo Starr are scheduled to perform at the event to mark 50 years since the Beatles first tour of America.

The three-and-a-half-hour show will be hosted by two-time Grammy winner LL Cool J.
