If you've got $4 million to spend on a birthday party, for yourself or for a very lucky friend/significant other, then this latest report from TMZ will give you an idea of exactly what kind of awesomeness that money can buy. Hint: the best kind, if you're into the hottest music acts of today.

The gossip outlet is reporting that Migos, J Balvin of "Mi Gente" fame, Diplo and more were part of the performers list at the recent 18th birthday celebration for one Thomas J. Henry Jr. The youngster is the son of a super successful (and wealthy) personal injury lawyer, who helped make this night in San Antonio one his boy will never forget. In fact, this is the same man who once dropped $6 million on his daughter's quinceanera. Talk about running up a (soft drink) bar tab. Check out some of the video highlights below.

Other celebrity guests who dropped by to help Thomas Jr. go crazy on his birthday included Austin Mahone, Lance Bass, Joanna Krupa and Adrienne Bailon. The question remains: what do you get someone as a gift when you're already spending $4 million on their birthday party? The answer is simple - a nice watch that he can wear on special occasions ... like the first time he gets behind the wheel of his brand-new Ferrari. 

It's safe to say that Thomas Jr.'s birthday is probably cooler than the next one you're going to have. On the bright side, you can always sit back, relax and check out our latest end-of-the-year list, featuring the biggest beefs that hip-hop saw over the course of this past year.
