Olympic skiing star Mikaela Shiffrin's BF Aleksander Kilde is doing everything in his power to keep his GF's spirits up ... after she suffered yet another devastating loss at the Olympics on Wednesday.
Kilde -- an Olympic skiing star himself -- posted a photo of Mikaela sitting on the mountain, head down, along with a touching note to his girlfriend ... after she was disqualified for missing a gate and skiing off the course during the competition.
"When you look at this picture you can make up so many statements, meanings and thoughts," Aleksander wrote.
