WATCH: 4th Impact Deliver Electrifying Mashup in X Factor UK Week 2 Live Shows

All-Filipino girl group 4th Impact (formerly 4th Power) wowed the judges with their mashup of "Sound of the Underground" by Girls Aloud and "The Clapping Song" by Shirley Ellis.

Compared to last week, the girls looked better this time and the production was on full force. Many have noticed that the group's get up last week was tacky and the stage was too bare. Good thing the Asian girl band was able to pull it off with their amazing vocals.

This week was no different. All the judges loved their performance despite the last minute decision on the second song. The group and their mentor Cheryl Fernandez-Versini was choosing between "The Clapping Song" and "Boom Clap." They all agreed to go with the first one.

In their video prior to the performance, the girls were shown touring London. They couldn't contain their delight seeing famous British landmarks like the Big Ben and the Buckingham Palace.

Simon Cowell said that they're great and they have always done great in the competition. He took a jab at Versini by saying that the song choice was narcissistic because it was her song, Radio Times reported. Versini said that it was the girls' choice not hers.

According to Digital Spy, both Rita Ora and Nick Grimshaw loved the performance. At first, Grimshaw wasn't sure if "The Clapping Song" was the right track to mashup with "Sound of the Underground" but during the performance he realized that it worked really well.

Meanwhile, Ora said that the great thing now was that she could see their individual talent even though they're sisters. The singer also had a short banter with Grimshaw when he said that she looked like she was dressed for Halloween.

Versini was very proud of her girls and said that their performance was fantastic. She also said that it was "fab."
