Looking to be having a lovely day, Hilary Duff was spotted tending to her always-busy agenda in Studio City, CA on Tuesday (November 30).
The former "Lizzie McGuire" star had quite the smile on her face as she rocked a pair of tight black leather pants while popping into a local office building for a midday meeting.
On the career front, Hil is readying for a public appearance tomorrow night (December 1) as she continues her book promotional efforts.
The 23-year-old is all set to greet her many fans while signing copies of her book ?Elixir? in Glendale, California at 7PM PT, as she tweeted, "Signing #ELIXIR at Borders in Glendale, CA in support of @LIFEbeatdotorg on World AIDS Day ? Dec 1 (7PM). See U There!"
