Michelle Williams reportedly attended a second memorial service to honor her ex Heath Ledger in Los Angeles on Saturday.

As reported by Entertainmentwise yesterday, Tom Cruise, Katie Holmes, Sienna Miller and Ellen DeGeneres were amongst the celebrities who attended the service to mourn the Brokeback Moutnain star, who died on a suspected drugs overdose late last month.

New reports claim that in addition to his family, the former Dawsons Creek star was joined by Josh Hartnett and Ledger’s other ex, Naomi Watts.

Musician Ben Harper is said to have performed a moving tribute to the late actor.

On Friday, Williams – who shares 2-year-old Matilda with Ledger – released a statement about the actors untimely death.

"My heart is broken. Please respect our need to grieve privately."
