Lakeside School is a private/independent school located in the Haller Lake neighborhood at the north city limits of Seattle, Washington, USA, for grades 5–12.

Lakeside sends 100% of its graduating class to four-year colleges. Its most famous alumni are Bill Gates and Paul Allen, founders of Microsoft, who got their start programming tic-tac-toe on a time-shared computer provided by the Lakeside Mothers' Association and the Lakeside Mathematics Department. Other famous alumni include the McCaw brothers, who built a family business into the McCaw Cellular telephone empire which they eventually sold to AT&T Wireless; actor Adam West; bestselling author Po Bronson; and former Washington State Governor Booth Gardner.

Lakeside School was founded in 1914 by Frank Moran as the Moran School on Bainbridge Island. In 1919, it moved to the waterfront Denny-Blaine neighborhood of Seattle and became the Moran-Lakeside School. In 1923 it moved to the present site of The Bush School in Washington Park and changed its name to the Lakeside Day School for Younger Boys soon thereafter. A few years later, Lakeside moved to its present location. It became coeducational upon merger with St. Nicholas, a Capitol Hill girls' school, in 1971.

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".
