Kim Kardashian showed off her morning workout on Tuesday, September 22—and the longtime KUWTK star, 39, was joined by some unlikely exercise buddies. Exes Tristan Thompson and Khloe Kardashian joined the KKW founder at the gym and Kim seemingly confirmed that their relationship is back on with her Instagram Story’s caption: “Am I 3rd wheeling hard?? #NoDaysOffCrew.” Kim’s Instagram Story featured an aerial shot of Khloé Kardashian and Tristan Thompson’s sneakers.
