"Blessed to have sisters. Focus on what's real," Jenner wrote alongside a photo of her with half-sister Khloe Kardashian on Friday. The reality stars spent the past few days skiing in Montana, avoiding the media spotlight.
Jenner also thanked her Instagram followers for their support. "Thank you for 18 mill. I love you guys."
The question of whether underage Jenner is dating Tyga has been scrutinized this week after Amber Rose blasted their rumored romance. A Twitter war ensued between Rose and Jenner's sisters, Khloe and Kim Kardashian.
Tyga has denied he is dating Jenner.
