Looks like we're going to have another custody battle on our hands!

Tila Tequila spoke to Extra about the death of her fiancee, Casey Johnson, claiming she knows it "was an accident." Why?

"Because she did have a sleeping problem," says Tila. And because she says Casey "was so excited for our life together. I know for a fact it was not suicide."

Tila ALSO reveals that she will seek custody for Casey's adopted daughter Ava. Currently, Ava is in the care of Casey's mother.

Says Tila: Casey's "last wish was to have Ava, have me have Ava."

So much drama! Who should little Ava go to?
