Jessica Simpson -- My Baby Can Fly!

Jessica Simpson's hubby is back to his baby-tossing ways, and Jessica could not be more thrilled about it.

Simpson posted this photo -- of Eric Johnson flinging their 1-year-old son Ace several feet in the air while in a swimming pool -- with the caption, "I was on a plane to NYC today and I missed out on this!!! I'm in LOVE with the 2 of them. #boyswillbeboys"

Back in April, Simpson took flack for posting a similar photo ... that showed Johnson tossing their daughter Maxwell into the air while walking on the beach.

Clearly they don't care what you think.
