African-American rapper Travis Scott will be supporting his girlfriend, Rihanna, for the singer's "ANTI" tour in North America while Samsung has unveiled a mobile website dedicated to promoting the "ANTI" album.

Scott, who is 27-year-old Rihanna's boyfriend, will serve as the opening act for the "ANTI" tour gigs that would take place in North America but will not perform during the European leg.

The "Meadow Creek" singer will be substituted by Canadian singer The Weeknd and 27-year-old Detroit rapper Big Sean once Rihanna arrives in Europe to continue the "ANTI World Tour," according to E! Online.

Meanwhile, tech giant Samsung has partnered with Rihanna to promote the singer's forthcoming album. Although the website can only be viewed through mobile devices, the ANTIdiaRy website offers viewers with a creatively complex activity that describes Rihanna's album-making process for "ANTI," according to Teen Vogue.

To provide more excitement, the "Umbrella" singer has even told the dedicated fan base that real keys have been hidden in various cities for people to find and use to unlock the different levels in the ANTIdiaRy website.

The first level has already been unlocked and investigated by several people. Titled "The Bedroom," the first level grants mobile viewers a chance see a spacious, white bedroom that can be somewhat creepy because of various illustrations located on the walls.

On a closer inspection, the drawings are actually a bit childlike and reveal airplanes travelling through Barbados, Africa and the United States.

Likewise, the places are indicative of Rihanna's history as a songwriter who was born in Saint Michael, Barbados and eventually invited by American record producer Evan Rogers to make music in New York City.

The other side of the wall has "Robyn Rihanna Fenty" written on it, which is actually Rihanna's real full name.

Moreover, another clue video in the ANTIdiaRy website features two kids playing the piano and a little girl entering the room. Rihanna, in a light blue dress, then walks toward the bedroom and looks at the children, especially at the small girl who is indicative of the singer's own childhood.

Rihanna's much-awaited "ANTI" album is set to be released on Dec. 4, 2015, on Tidal and the world tour to promote the album will start on Feb. 26, 2016 at the Viejas Arena in San Diego.
