Well this seems likes an unlikely friendship -- Sandra Bullock was just spotted hanging out with Camila Alves ... who is married to her ex, Matthew McConaughey. Huh?
The Oscar winner and her son Louis, 2, spent some time with a very pregnant Mrs. McConaughey and her two kids Vida, 2, and Levi, 4 (not pictured), in New Orleans on Tuesday.
Sandy lives in The Big Easy and the McConaughey family is in town while Matthew shoots his new film "The Dallas Buyer's Club."
The group bundled up to enjoy the fall afternoon, checking out a performance by the Warren Easton Charter High School band.
Sandra and Matthew starred together in the 1996 flick "A Time to Kill" and dated back in the '90s. We love that the two have remained friends ... and that their kids will grow up to be as well.
