Michael Jackson's defence team is getting ready to call witnesses as the prosecution in his molestation trial begins to wrap up.

CNN, citing an unnamed source "familiar with the case," reported on Wednesday that Macaulay Culkin and two witnesses whom the prosecution alleged were molested by Jackson will be "among the first" to testify in his defence.

It is expected that the first round of defence witnesses will be used to counter-argue the prosecution's allegations that Jackson "groomed" boys for molestation.

The prosecution's last scheduled witness began testimony on Wednesday morning.
