"Ur So Gay" is the song released by pop singer Katy Perry, produced by Greg Wells and engineered by Drew Pearson. The song was Perry's first major label release, and was later placed on her major label album, One of the Boys. Capitol Records offered the song as a free download on their website. The song failed to enter the Billboard Hot 100.

When asked about her debut single, Perry said the song was a "soft hello". The song "wasn't meant to be a big single or show what the album is going to be all about. That was for my Internet bloggers, so I'm not coming out of nowhere." Perry's A&R Chris Anokute confirmed this by saying that they had no plans for radio coverage but just wanted to put this "novelty" song out online as an introduction to see "what the attraction was". As expected, sales were low but Anokute said the single did well in terms of building a press story.

For the release of the single, Perry's label told her to include a cover. She originally wanted to cover a Queen song, but couldn't think of a particularly club-worthy song. While at a club with her friends, The Outfield's "Your Love" was played. Perry said that when the song came on, every girl in the place went onto the dance floor, and she wanted to have that same effect.

Once a coastal city near the mouth of the Euphrates on the Persian Gulf, Ur is now well inland, south of the Euphrates on its right bank, 16 kilometres (9.9 mi) from Nasiriyah.

The city's patron deity was Nanna, the Sumerian moon god, and the name of the city is in origin derived from the god's name, URIM₂^KI being the classical Sumerian spelling of LAK-32.UNUG^KI, literally "the abode (UNUG) of Nanna (LAK-32)".

The site is marked by the ruins of the Ziggurat of Ur, which contained the shrine of Nanna, excavated in the 1930s. The temple was built in the 21st century BC (short chronology), during the reign of Ur-Nammu and was reconstructed in the 6th century BC by Nabonidus. The ruins cover an area of 1,200 metres (3,900 ft) northwest to southeast by 800 metres (2,600 ft) northeast to southwest and rise up to about 20 metres (66 ft) above the present plain level.

Katheryn Elizabeth Hudson (born October 25, 1984), known by her stage name Katy Perry, is an American singer, songwriter and actress. Perry grew up with gospel music, and during her first year of high school she pursued a music career as Katy Hudson, releasing her first studio album called Katy Hudson which failed to chart. She recorded a solo album later, which was never released. After signing with Capitol Music Group in 2007, her fourth record label in seven years, she adopted the stage name Katy Perry.

She first gained recognition with the release of her first mainstream album, One of the Boys in 2008, which spawned three Billboard Hot 100 top-ten songs—"I Kissed A Girl", "Hot n Cold" and "Waking Up In Vegas". Perry supported the album with her Hello Katy Tour. In 2010, her third studio album, Teenage Dream (2010), which topped the Billboard 200 chart, and spawned five number one singles—"California Gurls", "Teenage Dream", "Firework", "E.T." and "Last Friday Night (T.G.I.F.)"—Teenage Dream was the only album (after Michael Jackson's Bad)—to do so, and the first female in history to achieve this milestone. She embarked on the California Dreams Tour, which grossed nearly $60 million worldwide. Perry re-released the album under the name of Teenage Dream: The Complete Confection on March 26, 2012, and the re-release has already spawned the number-one single "Part of Me".
