Wearing all black, Seal was quite the cool customer when he jetted out of LAX on Wednesday. We gotta hand it to him -- the dude knows how to look badass even on an airplane. And who knows -- with that guitar in tow -- maybe he will serenade some lucky ladies on the flight!

On Saturday, the 50-year-old singer reunited with ex Heidi Klum in Malibu to celebrate their daughter Lou's birthday. The previously contentious exes seemed to put their differences aside for the afternoon and even shared a friendly kiss.

Looks like they have kissed and made up!

Seal and Klum began dating in early 2004 and became engaged in December 2004 on a glacier in Whistler, British Columbia, The twosome married on May 10, 2005 on a beach in Mexico and have three biological children together. On January 22, 2012, the couple announced that they were separating. The Project Runway host filed for divorce from Seal three months later on April 6, 2012 and has been dating her bodyguard Martin Kristen since September 2012.
