I need your guys opinion.. My friend just found out she's pregnant.

The beginning of March was the last time she had intercourse with her boyfriend of two years. They split and she got with some one new. Her last period was March 20-25, her and her new be got together right after her period. Now April 20 she found out. The doctor says she got pregnant around April 6. Now the new bfs aunt is denying that it's his baby. What do you think???
