She’s in a bitter battle with her father, and it appears as if Lindsay Lohan let their grudge get in the way of her willingness to attend her late grandfather’s funeral.

The “Mean Girls” actress was spotted out shopping and walking the streets of Soho with a guy friend on Monday (September 1), skipping her grandfather's services in Long Island.

LiLo’s grandpa passed away last Thursday after battling cancer, her father Michael Lohan told press last week.

“I notified all my kids and my lawyer notified Dina’s attorney,” he told OK! magazine. “Let’s see if she has the decency and respect to bring my kids to the wake and funeral. This will show her true colors.”

Michael has since confirmed Lindsay’s absence from the wake – surely ready to use the latest incident as ammo in one of his soon-to-be-heard public rants.
