TMZ has obtained the memorial program … which provides more detail about what actually went down behind closed doors.

According to the program — which featured a black-and-white headshot of the late star looking over her shoulder — there were many more speakers than the ones we previously told you about.

Connie Britton, Charles Esten, Evan Ross, Jeff Beacher, and Sanoe Lake are just a few of the bold-faced names who honored Hayden. Sources also tell us Caroline D’Amore‘s young daughter sang as well.

The program also includes a “Special Thanks” section … with some individuals and brands getting special shoutouts.

The first name is Wladimir Klitschko — Hayden’s ex-fiancĂ© and the father of her child. Cameron Diaz’s wine, Avaline, and the lifestyle and clothing brand Aviator Nation are also mentioned.

The memorial went down Saturday at Malibu Pacific Church … and we shared photos of the famous faces who showed up. Our sources said there were about 150 guests total.

The ceremony was followed by a private reception at an estate in the famous Malibu Colony enclave.

We broke the story … Hayden died on August 16 after being found unresponsive in a South Carolina rental property … and law enforcement sources told us they think she took a black-market oxycodone pill laced with fentanyl.

Hayden’s dad, Skip, attended the memorial, but her mother — Lesley Vogel — didn’t. While we heard from sources that she wasn’t invited, a source close to Lesley denies it … instead claiming she did not attend due to a family emergency.

Brian and Zach Hickerson also weren’t there. Brian was Hayden’s longtime BF, and the brothers were the ones who found her dead.
