Hayden Panettiere jacket boots denim airport la lax blonde smile

And she's got a big smile on her face!

Hayden Panettiere looked happy as can be upon arriving at LAX last night, but she sounded less enthused when recalling the night a burglar tried to break into her home to E! News:

    "It was the scariest moment of my life. The alarm was going off and off and off, but no one was coming. As soon as I knew what was happening, I grabbed my Taser and my cellphone and locked myself in the bathroom. I called a friend that lived close and I called my dad. I was sitting and shaking by the toilet, but then was like, 'Screw this! I'm not waiting for somebody to come barging in.' So I crawled out the window. I'm running with this Taser in my hand and I run around the corner of the house and I've got like seven police with sniper rifles and lasers on me. I'm going, 'Don't shoot! Don't shoot me, please!'"

Crazy! Meanwhile, check out a new clip from Scream 4 (out April 15) below with Hayden and Emma Roberts:
