ET spoke with Larry Birkhead Monday outside of the courthouse where the Anna Nicole Smith drug trial was underway.

Larry told ET the following about Monday's testimony:

"I just want the truth. I didn't come to court saying I want to throw somebody [in]to the fire or take up for anybody, I just came here to tell what I knew … I basically felt like what I was doing was establishing a timeline and I felt like we were all kind of over the map with different things and I think we kind of went off chart a little bit."

The father of Anna Nicole's daughter Dannielynn also told reporters that his young daughter was "very smart" and healthy, adding, "My daughter's flourishing. She's doing everything that kids do, and then some, and [I've] been told by several doctors that she's quite advanced."
