Liam Hemsworth kept a low profile while catching a flight out of LAX on Wednesday. The actor stayed casual in jeans and a NY Yankees baseball cap while making his way through security. Liam is likely having a rough week, as he's been in the center of a breakup (with ex-fiancée Miley Cyrus ) and possible new romance (with Mexican singer Eiza González). Reps for Liam and Miley confirmed earlier this week that the couple officially called off their engagement , and Liam was rumored to have been getting pretty close with Eiza during a trip to Las Vegas over the weekend. But we've also spotted the maybe-single, maybe-not star spending time with another special lady — his mom, Leonie  — following news of the split.
