Beyoncé fans have sent Twitter into meltdown amid rumours that the heavily pregnant singer may have gone into labour.

The 35-year-old is due to give birth to twins any day now and an increased security presence at a Los Angeles hospital has led many to believe that the process has already begun.

According to Hollywood Life, an insider said, 'Beyonce’s security was seen leaving her Beverly Hills home this morning carrying two baby seats to a hospital in West LA 

'Beyonce’s due date was yesterday and she has been seeing her OB/GYN on a regular basis at a different location. This trip to this hospital is unique.'

Fans have taken to Twitter to express their excitement about the speculation.

It was previously reported that the singer has converted part of her house so she could deliver her twins form the comfort of her own home, however, latest reports suggest that she will in fact be giving birth in hospital.

In February, Beyonce's husband, Jay Z, announced that the couple were expecting twins.

The rapper said: 'We would like to share our love and happiness. "We have been blessed two times over."

"We are incredibly grateful that our family will be growing by two, and we thank you for your well wishes. – The Carters."

The couple, who married in 2008, are already parents to their five-year-old daughter, Blue Ivy.
