“Only Girl” was released as the lead song of Rihanna’s fifth studio album called “Loud” on September 10, 2010. It was composed by Crystal Johnson, Norwegian production couple Sandy Vee and StarGate, also produced by Vee and StarGate.
“Only Girl” is up-tempo dance music with elements of Europop in it. The shooting for this song was done at a spot just outside the city of Los Angeles. The song has been performed live by Rihanna as part of many shows.
The video impersonates the lighthearted lyrics to the song, which recommends that she is really the "lone girl in the planet". The greater part of the video shows Rihanna frolicking around hillsides wearing a sweater and short skirt, a bustier and small flowery skirt, and finally, "boy shorts" and a white bra.
