A representative for Ashlee Simpson has denied claims the star was drunk during a radio interview yesterday – insisting she was “simply just tired”. The 23-year-old appeared on Washington D.C.’s Hot 99.5 Kane In The Morning show, but attracted attention because she appeared to have trouble speaking and slurred her words.

But her spokesperson is adamant Simpson’s behavior was due to her busy promotional schedule. A representative for the star says, “Ashlee was absolutely not intoxicated this morning on Hot 99.5. She has been working extremely hard traveling across the country to promote her upcoming new album by performing at night and waking up very early the next day to do radio interviews in the morning – like any of us would be – she was simply just tired.”
