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.
