A Christmas tree is a decorated tree, usually an evergreen conifer such as pine or fir, traditionally associated with the celebration of Christmas. An artificial Christmas tree is an object made to resemble such a tree, usually made from polyvinyl chloride (PVC).

The tree was traditionally decorated with edibles such as apples, nuts or dates. In the 18th century, it began to be illuminated by candles, which with electrification could also be replaced by Christmas lights. Today, there is a wide variety of traditional ornaments, such as garland, tinsel, and candy canes. An angel or star may be placed at the top of the tree, to represent the host of angels or the Star of Bethlehem from the Nativity.

The custom of the Christmas tree developed in early modern Germany with predecessors that can be traced to the 16th and possibly the 15th century. It acquired popularity beyond Germany during the second half of the 19th century. The Christmas tree has also been known as the "Yule-tree", especially in discussions of its folkloristic origins.

Stefani Joanne Angelina Germanotta (/ˈstɛfəniː dʒʌrməˈnɑːtə/ STE-fə-nee jurr-mə-NAH-tə; born March 28, 1986), known by her stage name Lady Gaga, is an American singer and songwriter. Born and raised in New York City, she primarily studied at the Convent of the Sacred Heart and briefly attended New York University's Tisch School of the Arts before withdrawing to focus on her musical career. She began performing in the rock music scene of Manhattan's Lower East Side, and was signed with Streamline Records by the end of 2007. During her employment as a songwriter for the record company, her vocal abilities captured the attention of recording artist Akon, who signed her to his label Kon Live Distribution.

Lady Gaga came to prominence as a recording artist following the release of her debut album The Fame (2008), which was a critical and commercial success that topped charts around the world and included the international number-one singles "Just Dance" and "Poker Face". After embarking on the The Fame Ball Tour, she followed the album with The Fame Monster (2009), which spawned the worldwide hit singles "Bad Romance", "Telephone" and "Alejandro". The album's success allowed her to embark on the eighteen-month long Monster Ball Tour, which later became one of the highest-grossing concert tours of all time. Her most recent album Born This Way (2011) topped the charts of most major markets and generated more international chart-topping singles, including "Born This Way", "Judas" and "The Edge of Glory". Besides her musical career, she involves herself with humanitarian causes and LGBT activism.

Brenda Mae Tarpley (born December 11, 1944), known as Brenda Lee, is an American performer who sang rockabilly, pop and country music, and had 37 US chart hits during the 1960s, a number surpassed only by Elvis Presley, The Beatles, Ray Charles and Connie Francis. She is best known for her 1960 hit "I'm Sorry", and 1958's "Rockin' Around the Christmas Tree", a US holiday standard for more than 50 years.

At 4 ft 9 inches tall, she received the nickname Little Miss Dynamite in 1957 after recording the song "Dynamite"; and was one of the earliest pop stars to have a major contemporary international following.

Lee's popularity faded in the late 1960s as her voice matured, but she continued a successful recording career by returning to her roots as a country singer with a string of hits through the 1970s and 1980s. She is a member of the Rock and Roll, Country Music, Rockabilly and Hit Parade Halls of Fame. Lee currently lives in Nashville, Tennessee.

Lee was born Brenda Mae Tarpley in the charity ward of Grady Memorial Hospital in Atlanta, Georgia. She weighed 4 pounds 11 ounces at birth. She attended grade schools wherever her father found work, primarily in the corridor between Atlanta and Augusta. Her family was poor, living hand-to-mouth; she shared a bed with her two siblings in a series of three-room houses without running water. Life centered on her parents finding work, their extended family, and the Baptist Church, where she sang solos every Sunday.
