Things are looking up for Robin Thicke and his son, Juilan. The singer turned 40 Friday and celebrated with his son, 6, by passing through the McDonald's drive-thru in Malibu.

Just a day after a 911 call from Julian's nanny was released -- of the young boy asking his caretaker to call the police to intervene on the day his father was supposed to pick him up for a custodial visit -- the pair appeared to be in a better place in their relationship.

In the recording of the call, Julian and the nanny ask police to intervene and "enforce a restraining order" because Julian was "crying and praying to the angels' at the thought of visiting with his dad.

But yesterday, Julian had a smile on his face as he peeked out the back window. Thicke's girlfriend, April Love Geary, was along for the ride.
