Byron James "B. J." Mullens (born February 14, 1989) is a British-American professional basketball player for Al Wasl Dubai of the UAE National Basketball League.
 He also holds British nationality due to his English mother.
 He was drafted 24th overall by the Dallas Mavericks and immediately traded to the Thunder in the 2009 NBA draft.
Naked and Sacred is Chynna Phillips' debut (and to date only) solo album, released in November 1995 three years after her departure from the pop group Wilson Phillips.
 She was the only member of the group to remain on her label, EMI, after they went on an indefinite break in late 1992.
 It was released on November 7, 1995 in the U.S. and was a commercial failure, selling only 22,000 copies in the United States according to Billboard.com.
 Chynna co-wrote 9 of the 11 tracks, featuring productions from Rick Nowels, Glen Ballard (who produced the majority of Wilson Phillips' previous work), and Desmond Child.
 According to Chynna, she was offered $1 million to record a solo album for EMI, and was dropped shortly after due to the album's disappointing sales.
The Invisible Kid is a 1988 American comedy film directed by Avery Crounse.
 The film stars Jay Underwood, Chynna Phillips and Karen Black.
Wilson Phillips is an American vocal group consisting of Carnie Wilson, Wendy Wilson, and Chynna Phillips, the daughters, respectively, of Brian Wilson of The Beach Boys and of John and Michelle Phillips of The Mamas & the Papas.
"Naked and Sacred" is a song by Rick Nowels, Chynna Phillips, Billy Steinberg performed by Chynna Phillips on her 1995 debut solo album "Naked and Sacred", and released as a single which charted at #15 in Australia and at #62 in the UK.
"Just to Hear You Say That You Love Me" is a song written by Diane Warren and recorded by pop singer Chynna Phillips for her solo debut album, "Naked and Sacred", released in 1995.
 The song was released as the fourth and final single from the album, and peaked at #64 in Australia in February 1997.
 In 1998, the song was recorded by country singer Faith Hill as a duet with her husband Tim McGraw.
 It was the second single from Hill's multi-platinum 1998 album, "Faith".
 The video for the song is notable for being composed almost completely of close-ups.
 Hill had recently given birth to her second daughter, and the child was resting in her lap during the video shoot.
 Because of this, the director was forced to use close-ups to avoid including the baby in the footage.
Moroccan nationality law is the subject of the Moroccan Dahir (decree) of September 6, 1958, official Bulletin Number 2394.
 In general, Moroccan nationality is transmitted by filiation (father and mother) or birth in Morocco.
 However, it gives the right to Moroccan males to transmit citizenship to their children and foreign wives, and since the last update, that is possible for women.
 The aim of the update was to follow Morocco's recent human rights reforms, most notably the Moroccan family code called, "Mudawana", which aimed to fight gender inequality.
 It has been done after much debate in the media.
Michelle Phillips (born Holly Michelle Gilliam; June 4, 1944) is an American singer, songwriter and actress.
 A native of California, she met and married John Phillips in San Francisco as a teenager, and went on to co-found the vocal group The Mamas & the Papas in 1965.
 The band rose to fame with their popular singles "California Dreamin'" and "Creeque Alley", both of which Phillips co-wrote.

Randy Phillips (born May 8, 1990) is an airman of the United States Air Force whose coming out in September 2011 following the repeal of the "Don't ask, don't tell" policy (DADT) garnered media attention.
 DADT had banned the service of openly gay members in the United States Armed Forces and Phillips used YouTube, under the alias "AreYouSuprised", to anonymously seek support and to document his life under the policy over several months.
 His videos included his coming out to his father and mother, which coincided with Phillips showing his face for the first time, and the accidental discovery of his anonymous web presence by his co-workers.
Chynna Gilliam Phillips (born February 12, 1968) is an American singer and actress, better known for being a member of Wilson Phillips.
 She is also the daughter of The Mamas & the Papas band members John and Michelle Phillips, and the half-sister of Mackenzie Phillips and Bijou Phillips.
