What baby? Beyonce is back to her best at rescheduled concert as she seems to dispel pregnancy rumours in tight costume!

The bump might not being showing yet, it has to be said. 

But there was nothing expectant looking about Beyonce when she took the stage at the Sportpaleis in Antwerp, Belgium. 

Beyonce was wearing a custom, hand beaded white peplum one-piece by designers Ralph & Russo which left no room for a bump, not even a tiny bump. 

Beyonce cancelled the original Tuesday date on her Mrs Carter world tour amid persistent rumours she is pregnant with her second child.

The singer blamed the cancellation on 'dehydration and exhaustion' and said her doctor had advised her to rest.

Myriad reports suggest that the 31-year-old is expecting her second child with husband Jay Z.

The New York Post newspaper claims 'multiple sources' told them Beyonce is pregnant following her attendance at the star-studded Met Ball last week, where the star's rumoured pregnancy was the talk of the night.

The pop superstar is said to have 'carefully' hidden her baby bump in a high-waisted Givenchy gown, but multiple photos have since surfaced of Beyonce sporting a growing stomach on her 65-date Mrs Carter Show world tour, which touched down in Dublin, Ireland, on Sunday.

She said: 'I would like more children. I think my daughter needs some company. I definitely love being a big sister.'

pressed on when she may have another child, she added: 'At some point, when it's supposed to happen.'

However a source tells People magazine the baby may not be on the way just yet: 'Beyonce and Jay are planning for another baby after her tour is over and things calm down just a bit.'
