Another guessing game for our dear Perezcious readers!
This is probably easier than our last installment, especially if you're familiar with celebrities who do a lot of philanthropic work.
But we don't think anybody does as much as this particular actress, who is pictured (above) playing with cheetah cubs at a wildlife sanctuary in Namibia — one of her daughters was born in the country, in fact.
She also serves as a UN ambassador and has her own foundation along with her equally famous and gorgeous husband!
Honestly, this is a pretty simple guess, so we don't want to give out too many clues.
Have you figured it out yet???
