Khloe Kardashian made her first public appearance Wednesday night since news of her highly publicized break up with Tristan Thompson surfaced earlier this week. Khloe decided to attend the grand opening of Pretty Little Thing on Melrose in West Hollywood Wednesday night where she put on a brave face and posed for pics on the red carpet.

Sources say Khloe considered canceling her appearance but didn’t want to let anyone down and made sure she kept her professional commitments. They say Khloe is devastated over the split with Tristan, but is trying her best to keep a brave face for her daughter, family and friends.

As for the woman who Tristan cheated with, Jordyn Woods (aka Kylie’s best friend), she’s reportedly moving out of Kylie's Hidden Hills mansion and in with her mom. Sources say the decision to move out was Jordyn’s and not Kylie or any Kardashian. However that’s probably the best for everyone.
