Brothers Maksim and Val Chmerkovskiy hosted Oil of Olay's "Get Lathered Up" event at Liquid Pool in Las Vegas earlier this week, and they showed off their buff bods in matching black swimsuits.

Earlier this month, Maksim, 33, was spotted getting cozy with Sports Illustrated swimsuit model Kate Upton. The "Dancing With The Stars" pro was once engaged to his co-star Karina Smirnoff and also dated fellow dancer Peta Murgatroyd. He was also once the star of the Ukrainian version of "The Bachelor."

Val, 27, has released a self-titled album. Tracks include "White Boy Boogie," "Eastern Europimpin", "Champagne Diet", "Brother", and "Mama."
