Kate Upton proved that she can be messy but hot at the same time.

Justin Verlander's girlfriend shared a selfie on her Instagram while getting her hair done on Saturday. People's Sexiest Woman Alive captioned the image, "I'm a natural blonde.. This isn't hair color the government is reading my thoughts! @traceycunningham1."

Naturally, Kate Upton's hot selfie generated a lot of comments, with one fan saying, "When I see you I feel happy your smile make my relax for inside I just want to see thank keep smiling."

Another said, "Beautiful whatever color it is."

One fan commented that Kate Upton maybe "pretty but not 'hot.'"

According to Daily Mail, "The 22-year-old was pictured during her appointment with celebrity hair colorist Tracey Cunningham, who counts supermodel Lily Aldrige and actresses Sara and Erin Foster as clients."

Meanwhile, in an interview with Vogue, "The Other Woman" actress Kate Upton shared her beauty tips for baseball fans.

She said when she goes out to support boyfriend Justin Verlander, she's always dressed in jeans and t-shirt.

"There's that moment when you think, I have to switch up my look. I can't wear a baseball cap and red lip anymore!" Kate Upton said, adding that female fans can opt for "easy waves, fresh skin, and a hint of black eyeliner and mascara" when they cheer for their respective teams.

Justin Verlander's girlfriend, Kate Upton, has been hounded with ugly rumors about her bad attitude and the nasty way she treats fans.

The NY Post ran a piece on Scott Smith, a collector of autographed Sports Illustrated magazine covers since 1954, who claimed that Kate Upton might be hot, but she's no sweetheart.

He claimed, "She's an absolute nightmare; just an ugly human being. I saw her alone, and she said, 'F*** me,' as if it was the worst thing in the world to be asked for her autograph. Those were the words she used, as if I was stabbing her in the heart."
