Question: Did Kesha ever perform live with Britney Spears? Passage 1:Wall was born in Liverpool and started his career with Blackburn Rovers as a youth player joining at under-14 level. In the summer of 2015 he signed his first professional contract after completing his scholarship with the academy. In November 2015, he joined Northern Premier League Premier Division side Skelmersdale United on a one-month youth loan. In the summer of 2016 he was released by Blackburn and joined League Two side Accrington Stanley on a one-year contract following a trial. He was recommended to the club by former Blackburn teammate and Accrington player John O'Sullivan. He made his first team debut for the club in August 2016 as a second-half substitute for Sean McConville in the 30 defeat to Crewe Alexandra in an EFL Trophy group-stage match. After struggling to break through into the match-day squad, he returned to Skelmersdale for a second loan spell in September 2016. In February 2017, he was sent out on loan again, joining Northern Premier League Division One North side Clitheroe on a short-term deal. He made a total of seven appearances in all competitions during the loan spell, scoring twice in a 43 away win over Ramsbottom United. In March 2017, he was on the move again joining Northern Premier League Premier Division side Marine on loan until the end of the season.

Passage 3:Minaj was one of the opening acts on Britney Spears' 2011 Femme Fatale Tour. She and Kesha appeared on the remix of Spears' "Till the World Ends", which peaked at number-three on the Billboard Hot 100. On August 7, 2011, Nicki experienced a "nip slip" during a live performance on Good Morning America. Minaj was criticized for wearing the low-cut shirt during her performance which led to the brief exposure of her breast on a live telecast. ABC apologized for incident. Minaj, while interviewed on ABC's Nightline show, apologized for the incident and denied that she intentionally sought to expose herself on live television as a publicity stunt. The incident attracted protest from the Parents Television Council. Despite this, Minaj continued to perform at high-profile events throughout 2011; Donatella Versace invited her to perform with Prince for the introduction of a Versace collection for H&M, and she performed "Super Bass" at the 2011 Victoria's Secret Fashion Show.
