Michael Jackson's children visited his hometown in Indiana to celebrate his birthday

According to TMZ.com, the occasion marked the first time the siblings have been seen together for a while as Paris has spent the past year at therapeutic boarding school Diamond Ranch Academy in Utah.

The aspiring actress became estranged from her family following her attempted suicide last June, but doctors wanted her to rekindle her bond with her grandmother Katherine Jackson and Prince and Blanket as they believed it would improve her mental health.

A source said previously: "Doctors want her to mend fences with Katherine, her siblings and other immediate family ... they think it's important to her healing."

The troubled star - who has grown close to her biological mother Debbie Rowe - was given the all-clear from doctors in May and is reportedly adamant she won't return to the $14,000-per-month private school in the Autumn.

However, Katherine - who is a co-guardian to Michael's three children alongside T.J. Jackson - doesn't think that's a very good idea and wants her to return.
