Michael Bublé 'secretly married to partner?'

Michael Bublé has sparked speculation of a secret marriage to his long-term partner Luisana Lopliato.

The couple, who met in 2008 and became engaged in November 2009, were expected to tie the knot this April. However, The Sun has today published a picture of the 'Hollywood' star wearing an alleged wedding band on his ring finger.

The rumoured joining follows last week's revelation that Bublé has purchased a £3 million home in the UK.

Bublé stated in November that he couldn't wait to marry his Argentinian lover.
