JLS and Rihanna have attracted huge crowds at this year's Radio 1's Big Weekend in Bangor, north Wales.

JLS played a 20-minute set including singles Beat Again, Everybody In Love and Only Tonight, where they were joined on stage by rapper Chipmunk.

Referring to a recent US trip, Aston said: "We've been away a while but it feels good to be back on home turf."

"Absolutely incredible - there were so many JLS supporters out there, t-shirts and banners," said Marvin.

Ortise added: "We've got so many fans and supporters out there - there's no place like home."

Rihanna, who has spent this month on tour throughout the UK, helped bring to a close the second and final day.

The singer, backed by a live band and backing dancers was introduced by DJ Scott Mills, who called her one of the "biggest stars on the planet".

She performed a number of tracks from her recent album Rated R, including Rude Boy, Hard and Disturbia.

Since gates opened at midday 20,000 music fans have seen performances from Paolo Nutini, Pixie Lott, Jason Derulo and Paramore.

Earlier in the day Essex singer Pixie Lott played a brief main stage set which included singles Mama Do and Girls & Boys.

Speaking to Newsbeat afterwards she said: "It was amazing - the crowd were so enthusiastic.

"I loved it, it's just so hot. We just got a ferry over from Dublin because we're doing the Rihanna tour at the moment."

Ke$ha and Biffy Clyro also played on the main stage at Vaynol Park.

Queuing outside before the gates opened Cara Edwards, 16, from Bethel said: "Paramore and Pendulum - we can't wait for those two. And Rihanna, she's really different compared to a lot of singers."

Catrin Jarvis, 16 from Llanrug said: "My sister got me a ticket in the ballot, so she's in my good books today."

Jack Wellings, 16 and Zack Dad, 16, who've both travelled from Shrewsbury said: "It's all about Pendulum and Biffy Clyro - I'm more of a rocky person. The pop stuff is fine though, we'll watch Rihanna."

On Saturday Florence and the Machine brought day one of Big Weekend to a close with a set which included a full choir and a guest appearance from Dizzee Rascal on their track You Got The Dirtee Love.

Highlights of day one included a short set from Canadian heart-throb Justin Bieber, Faithless headlining the second stage and Cheryl Cole's debut festival performance as a solo artist.

The Radio 1 event is Europe's biggest free festival with more than 60 artists playing to 40,000 fans over two days.
