Floyd Mayweather Jr. and Manny Pacquiao have turned to social media to promote their fight in a battle for online supremacy.

Mayweather, posing for a selfie with Justin Bieber, has invested in Shot, a photo-sharing social media application.

Mayweather's last bout was against Marcos Maidana of Argentina on September 13, 2014 at The MGM Grand in Las Vegas. Mayweather dominated with a 12 round unanimous decision, retaining his WBA welterweight belt and WBC welterweight and super welterweight world titles.

Most of Pacquiao's social media posts evoke his Christian faith and devotion to family. He is photographed with his wife Jinkee during mass in the Quiapo district of Manila on November 20, 2009.

The Filipino superstar hugs his daughters Princess (R) and Queen Elizabeth during a press conference in Manila on November 20, 2010. Family snaps make up much of his Instagram feed.

Pacquiao most recently won a unanimous decision over Chris Algieri of the United States during the WBO world welterweight title at The Venetian on November 23, 2014 in Macau.
