All three sisters starred in the film Daddy's Little Girls (2007), for which they released the single "Daddy's Girl".

Career

2005–2010: 3mcclaingirls 
In 2005, the sisters' father had a friend over who was a music executive. The music executive heard the sisters sing and encouraged director Rob Hardy to audition China for his 2005 feature film The Gospel. China was cast as the character Alexis and her sisters were in the supporting cast. The sisters then became serious about a musical career and formed the girl group called the 3mcclaingirls.

They recorded their first song, "Silly Games". The song was produced by their father, Michael McClain, and written by their mother, Shontell McClain. In 2006 China joined the main cast of Tyler Perry's House of Payne as Jazmine Payne and Sierra made guest appearances. In 2007 the group starred in the film Daddy's Little Girls as the James sisters. In 2008 the group recorded the song "Daddy's Girl", inspired by the movie, and released it exclusively on MySpace.

They also continued pursuing their acting careers separately, making various appearances in films and on television.

2011–2012: McClain Sisters and Hollywood Records 

The sisters originally planned to use the name III as their group name, the number representing the three McClain girls in the group, but that idea was scrapped. They instead changed their group name to the McClain Sisters. That same year China landed her own show on the Disney Channel called A.N.T. Farm. On October 11, 2011, the A.N.T. Farm soundtrack was released on which the group released two songs: "Perfect Mistake" and "Electronic Apology". The group had plans to release their debut album with the record label but never did.

The music video premiered on March 25, 2012, during an episode of Austin & Ally. It was also a featured song for Disney's Friends for Change. The music video later premiered online on March 26, 2012.

On March 5, 2013, the soundtrack album Shake It Up: I Love Dance was released for which the group performed their single "Sharp as a Razor." In December 2013, China announced on Twitter that A.N.T. Farm would be ending after its third season. Shortly after this announcement, the McClain Sisters parted ways with Hollywood Records. After leaving the record label, the group changed their name from the McClain Sisters to simply McClain. In December 2013, the group performed once again at the Hollywood Christmas Parade at Universal CityWalk Hollywood. The group released an official lyric video for their single "He Loves Me" on YouTube on December 14, 2013.

The song then became available on iTunes on February 20, 2014. On April 26, 2014, McClain performed at the pre-show for the 2014 Radio Disney Music Awards and presented an award.

In June, the group performed at Thirst Project's gala. On June 29, McClain had their first headlining concert at the House of Blues in Anaheim, California. One month before the show in May, the sisters promoted their concert by performing on the talk show Home & Family.

From the summer to the fall of 2014, the group toured the United States, performing at various state fairs including: the Wisconsin State Fair, Delaware State Fair, West Virginia State Fair, North Carolina State Fair, York Fair, and the Ohio State Fair. In August 2014, McClain also performed at Six Flags Over Texas, and the 19th Arthur Ashe Kids' Day. Later that year, McClain released their Christmas song called "The Holiday Song" on December 13.

In 2015 the group released the song "Clip My Wings" which was featured in the film The Sparrows: The Nesting and on the film's soundtrack The Sparrows: Now & Then.
