"Randomly waking up in the middle of the night sucks," she wrote on her page.

It seems like this could be a continuous issue since she wrote something on Tuesday that appears to connect with her previous post.

"I wish I could stay in bed all day," she wrote.

While Selter is known for tweeting little bits of personal problems she may have in her life, she is more commonly known for her photos that show off how hard she works to make her body petite yet muscular mainly in her backside.

On Sunday, she posted an closeup shot of her behind as she wears tight black sweats. She's also wearing tennishoes as she bends over outside in broad daylight with one leg up in the air.

Selter captioned the picture, "and time for some booty work outside."

While the model is famous for her voluptuous behind, she also posts images of her legs and abs in mirror selfies as well as more professional types of pictures. A new photo shows her in a green sports bra with matching shoes as she stands outside with buildings around her. She stares off in the view as the sun appears to be close to setting.
