Shiloh Jolie-Pitt takes the plunge with her latest fashion statement - a pair of boy's swimming trunks.

The head strong four-year-old made a big splash by ditching a feminine swimsuit for baggy swim shorts, while playing by the pool during a family weekend in Berkeley, California.

But the exclusive shots of the tomboy on UsMagazine.com aren't phasing her super-sexy mom.

"It's not my choice. I have a very strong-willed four-year-old girl, who tells me what she wants to wear and I let her be who she is," said Angelina Jolie.
