Making the most of her Thursday evening, Ashlee Simpson played host for the big Samsung Galaxy S III event in New York City last night (July 19).

The “LaLa” songstress hammed it up with Nick Millhiser and Alex Frankel of Holy Ghost as shutterbugs snapped pictures of her fabulous wispy white blouse and red leather shorts.

And despite the rumors of a sisterly spat between Ashlee and Jessica Simpson over Jess’ baby, it turns out things are just fine.

A tabloid report claimed that Ashlee “is jealous of the attention and the money Jessica is getting for losing her baby weight. She’s always had a chip on her shoulder about growing up in Jessica’s shadow. But when [her son] Bronx was born, Ashlee felt like she had a leg up, because all eyes were on her.”

However, a family friend definitively declared, “That’s hilarious. Ashlee and Jess are extremely close and were together all day on Jess’s birthday.”
