Sunday night saw Justin Timberlake and Jay Z share the headline slot with a joint Legends Of Summer gig after appearing individually on Friday and Saturday respectively.
Kicking off their set with a rendition of Holy Grail - which they also performed during Jay Z's slot on Saturday - the talented duo took it in turns to play some of their biggest hits.
Performing a number of tracks from his new album Magna Carter Holy Grail, the rapper husband of Beyonce Knowles thanked the crowd for making the record his first number one album in the UK.
The record ousted Mumford & Sons' Babel, which enjoyed surging sales because of the folk-rock band's appearance at Glastonbury Festival last month.

Jay-Z's 13-track LP comfortably outsold its nearest rival, Rod Stewart's Time, but despite previously enjoying seven top 40 albums as a solo artist, the star had never reached the summit before.
His personal best before Magna Carta Holy Grail - featuring guest appearances from Justin Timberlake, Frank Ocean and wife Beyonce - was number 4 in 2009 with Blueprint III, while his joint effort with Kanye West, Watch The Throne, peaked at number 3 in 2011.
Also appearing at the Yahoo! Wireless Festival on Sunday were the likes of will.i.am, Katy B, Nas and Jessie Ware, while TV presenters Zoe Hardman and Caroline Flack were seen chilling out in the VIP area.
