Calvin Harris was among the stars from the world of dance music, pop and rock who took to the T in the Park stage for Scotland's biggest music festival.
He was joined at Strathallan Castle estate in Perthshire by Dizzee Rascal who rocked the house with a performance of his new track Hype.
The Scottish DJ, whose real name is Adam Richard Wiles, has been the subject of numerous headlines since he and singer Taylor Swift split a few weeks ago after 15 months of dating.
She has been photographed kissing and cuddling British actor Tom Hiddleston in various countries, including America, Australia and Italy. The couple have been dubbed 'HiddleSwift' by fans.
Calvin's new track Ole with John Newman has already sparked a good deal of discussion on social media as fans suggest it may have been sparked by Shake It Off star Taylor.
Ole, which Calvin wrote, is about a broken relationship.
The DJ, Jess Glynne, The 1975, Tinie Tempah and the Bay City Rollers all performed on the second night for tens of thousands of revellers.
Saturday's T in the Park line-up also included Tom Odell at King Tut's Wah Wah Tent, the Kaiser Chiefs on the Radio 1 Stage and Bastille taking to the main stage.
Stuart "Woody" Wood of the Bay City Rollers said the group's T in the Park gig will be his last with the band.
The guitarist, who enjoyed massive fame with the Rollers in the 1970s before a successful comeback last year, announced the news hours before the band took to the stage.
There have been rumours of a dispute between members of the veteran Scottish group, whose hits include Shang-A-Lang and Bye Bye Baby.
Woody wrote on Facebook: "Hi All ... just to say TITP is my last gig. Disappointed is an understatement but out of my control. Details will follow in due course ... love as always, Woody x."
The musician was quickly inundated with messages of support and sorrow from fans across the world.
Band members Les McKeown, Alan Longmuir and Woody revealed they were getting back together last autumn and tickets for a series of reunion gigs in Glasgow in December sold out in minutes.
Formed at the end of the 1960s, the group had a huge following at home and abroad with their distinctive tartan outfits and upbeat pop tunes.
They split in 1978, with bitter battles over money between band members and managers dragging on for decades, but set in motion a new wave of "Rollermania" with their recent return to the concert circuit.
Les will release a solo album on August 22 called The Lost Songs.
