Britain's Got Talent returned last night with a sensational sibling frenzy. Sibling performers brought a wave of fascination in Saturday's first episode of 2015.

While the dangerous yet refreshingly talented roller-skating duo Billy and Emily England soared their way into the live finals after wowing the judges, there were mixed emotions as siblings Calum and Jade Scott performed as solo artists.

Billy and Emily's fate was tied to one another as they performed together for and impressed the judges, however Jade and Calum, singing siblings from Hull, were forced to go head to head as they sang one after another to impress the panel.

Viewers saw Jade fail to win the backing of the judges with her rendition of "Say You Love Me" by Jessie Ware and "With Or Without You" by U2.

Nonetheless, Simon, Amanda, Alesha and David were all more than impressed when Calum, 26, took centre stage and belted out his unique version of "Dancing On My Own" by Robyn.

Minutes after his sister was sent home for her efforts, Calum appeared nervous as he took the stage but was overwhelmed after he earned a standing ovation from the audience.

Calum's sensational singing voice bagged him a guaranteed place in the live semi-finals as Simon struck the golden buzzer. Jade overlooked her sorrow and proudly hugged her brother on stage as the crowd cheered and confetti filled the stage.

Simon admitted, "The version was sensational, which shows to me that you're more than a singer, you're an artist and that's why you got the buzzer."

An impressed David said, "That was great. I am no expert on singing but you know when someone is taking you on an emotional journey. You have a real talent and a great recording voice as well."

After the audition, Simon praised the recruitment officer's talent as "sensational," claiming that he had, "never heard a guy with the talent you've got" during his time as a judge on Britain's Got Talent.

The UK's much-loved talent show may have only returned to television screens this weekend but it's no surprise that Calum has already emerged as favourite to win this year's competition.
