Maria Sharapova: Bikini Weekend with Chelsea Handler ... Tests Positive For Hotness

Now that she's got free time (thanks to that suspension) tennis superstar Maria Sharapova ran for the border this weekend ... spending her Easter in a bikini with Chelsea Handler.

The two were spotted in an exclusive area of Cabo San Lucas -- where they took in some sun, took out a boat ... and even rapped together.

The 28-year-old was provisionally banned from tennis after testing positive for the banned substance meldonium ... but it seems she's treating the whole thing more like a vacation than a punishment.

Ole!!!
