Chris Bosh -- Reunited with Daughter ... Thanks to All-Star Weekend

Chris Bosh claims this weekend was the "BEST" All-Star weekend ever -- because it took place in Orlando ... giving the Miami Heat star a chance to spend some quality time with his 3-year-old daughter.

As we previously reported, Bosh has been battling his baby mama Allison Mathis in family court -- claiming she's been making it impossible for him to be a dad ... putting up a fight every time he wants to see his kid.

But yesterday as he was leaving an Orlando court, Bosh was in good spirits -- telling TMZ, he missed the slam dunk contest on Saturday because he was hanging with his daughter.
