Tila (real name: Tila Nguyen), 28, is currently engaged in a war of words with pals of the late Johnson, who are accusing Tila of using the Johnson and Johnson heiress for media attention.

Earlier this week, Tila was in tears as Nicky Hilton (godmother to Johnson's daughter Ava, 3) and Bijou Phillips went to Tila's L.A. home to retrieve dogs belonging to Johnson.

She called the cops and later blasted them as "heartless" on Twitter and alleged they were putting the dogs to "sleep." (Phillips has denied Tila's claim.)

"Trust me. My Wifey is in Heaven Laughing Her Ass Off at these Posts I'm Doing," Tila wrote Friday. "I know her better than anyone."
