During an online chat with fans in April 2015, Sia revealed that the album would "probably" be released in early 2016, but possibly before the end of 2015. The
Target-exclusive deluxe edition of
This Is Acting features a song by the name of "Summer Rain". It is believed that this song was rejected by
Christina Aguilera. An alleged track list for
Aguilera's eighth studio album was leaked early in 2015, and the fifth track was entitled "Summer Rain", suggesting that she was planning on recording and releasing a song dedicated to her daughter with the same name. Sia is also listed as one of the producers on the record. Now that a song whose title is identical to Aguilera's alleged track name has been realized and placed on Sia's extended album, it is thought to have been planned for Aguilera initially, but declined shortly after. On 7 November 2015, Sia performed "
Alive" and "
Bird Set Free" on
Saturday Night Live; the episode was hosted by
Donald Trump. She performed "Alive" on
The Ellen DeGeneres Show and
The Voice on 1 December, and again on
The X Factor in the United Kingdom on 6 December. She further appeared on
The Graham Norton Show on 11 December, where she sang "Alive", and on 27 January 2016, she performed "
Cheap Thrills" on
The Tonight Show Starring Jimmy Fallon. In February 2016, Sia appeared on
The Late Late Show with James Corden, in the
Carpool Karaoke segment with
Corden. A deluxe edition of
This Is Acting was released on 21 October 2016 featuring seven new tracks, including three brand new tracks: "Confetti", "Midnight Decisions", and "Jesus Wept", as well as the single remix of "Cheap Thrills", the
Alan Walker remix of "
Move Your Body", and the solo and
Kendrick Lamar-assisted versions of "
The Greatest".
Singles In September 2015, Sia confirmed the album's lead single "Alive" would be released later that month and was originally written for
Adele; the English singer and songwriter co-wrote but "rejected" the song at the last minute. The album's release date, 29 January 2016, was confirmed in early November 2015. "Cheap Thrills" was released as the album's second official single on 17 December 2015, and it was originally planned for

Kendrick Lamar. "Move Your Body" was released as the third single from the album on 6 January 2017. The song was originally planned for
Shakira. "Reaper" was released in Australia as the fourth single from the album on 29 May 2017. "

TikTok videos.
Promotional singles "
Bird Set Free" was released as the first
promotional single along with the pre-order of the album on 4 November 2015. The song was originally written for
Pitch Perfect 2 but it was rejected in favor of "
Flashlight". The song was then pitched to Rihanna. After being rejected, it was then recorded by Adele but did not make the cut for her third studio album,
25. "One Million Bullets" was released as the second promotional single on 27 November 2015. The song is the only one on the album that was not pitched to another artist. "
Reaper" was released as the fourth promotional single on 7 January 2016. The song was written by herself and
Kanye West for Rihanna, but Sia decided to keep it.
