On October 31, 2005, Britney Spears released the single And Then We Kiss. The original song failed to make the cut on her fourth studio album In the Zone, so it was later remixed by Junkie XL to be included on B in the Mix: The Remixes and also the EP Key Cuts from Remixed. The remix was released as the promotional single from the album in Australia and New Zealand. The original version by Taylor leaked online in September 2011.
The Junkie XL Remix of "And Then We Kiss" is a euro-trance song with influences of techno and usage of dance-rock guitars, synthesizers and symphonic strings. The song failed to appear on any major charts. However, it peaked at number fifteen on the US Billboard Hot Dance Airplay. The song appears in Dance Dance Revolution Supernova 2.

(Credits to @PokemonSpears) On October 21, 2018, Britney Spears performed the last show of her Piece of Me Tour at the Circuit of the Americas in Austin, Texas as one of the two performers of the Grand Prix (the other one being Bruno Mars).
The tour brought a watered down version of her Las Vegas residency to several cities of United States and Europe. This last show was isolated from the two previous legs, and it happened after the new residency Domination, set to kick off in 2019, had already been announced.
Domination was ultimately cancelled in early 2019 and she's been on a hiatus ever since, so this show marks her last performance of the 2010's decade, and her latest performance so far.

Today in 2009, "3" debuted at #1 on the Billboard Hot 100 and became Britney's 3rd #1. It entered at #14 on the US Billboard Bubbling Under Hot 100 the prior week. It made Britney the first artist in over three years to debut at the top position and the only non-American Idol artist in eleven years to do so. It was the fifteenth song in the chart history to debut at the top position and also the shortest title for a song reaching the top of the Billboard Hot 100.

"Womanizer" debuted at #96 and jumped to #1 today in 2008. It broke the record for largest jump to number one and largest jump to any position in the history of the chart, previously held by T.I.'s "Live Your Life" (feat. Rihanna) and Beyoncé and Shakira's "Beautiful Liar", respectively. The record was later broken by Kelly Clarkson's "My Life Would Suck Without You".
