What could make our beautiful female rap star Iggy Azalea look so serious??

Did Iggy Azalea find solace from the Nick Young drama on a horse ... not sure why she had such long face on but the rap star who's a big equestrian
enthusiast took out her frustrations Wednesday by saddling up at a private riding trail in Calabasas ... alone.
As for Nick ... we're told he's fiercely trying to save his relationship with Azalea ... if she makes up her mind about that we will be happy for them!
