WATCH: Adele totally breaks down during show over Orlando victims

Singer-songwriter Adele is well known for her emotional performances, but her concert in Belgium last night was particularly poignant as she struggled to fight back tears while speaking about yesterday's mass shooting in Orlando.

The Hello singer dedicated her entire performance to those killed when lone gunman Omar Mateen opened fire in popular gay nightclub Pulse in the early hours of Sunday morning, killing 50 and wounding 53.

She said: “I would like to start tonight by dedicating this entire show to everybody in Orlando and at Pulse nightclub last night.”

“The LGBT community…they’re like my soulmates since I was really young,” she explained.

The Grammy-winner's voice wavered with emotion as she spoke and she eventually turned away from her audience and cried for a moment before composing herself and continuing her show.

Adele is one of a series of well-known faces – including Adam Lambert and JK Rowling – to voice their upset over the incident.

Last night’s Tony Awards ceremony was also devoted to those who lost loved ones in the attack, with host James Corden paying tribute to those who died in his opening speech.
