Eminem made an unannounced appearance at the WSJ Innovator of the Year Awards on Nov. 5 to honor his mentors, Dr. Dre and Jimmy Iovine, but it was his physical appearance that really took fans and guests by surprise.

Dressed in all black, the 42-year-old’s gaunt appearance and noticeably thinner frame have some worried.

Regardless of what’s causing Shady to look frail, he was said to be in good spirits.

Meanwhile, critics are making similar observations about Mary-Kate Olsen after she attended the 2014 World of Children Awards in NYC with her sister Ashley last night, Nov. 7.

Though the ladies opted to wear minimal makeup to the star-studded event, some are speculating it’s more than a “fresh face” that’s responsible for MK’s highlighted cheekbones.
