Why did Priyanka Chopra and Nick Jonas choose surrogacy?

To be fair, it's their personal decision, but if you're still curious, TMZ said that the couple chose surrogacy due to their extremely hectic schedules. Priyanka Chopra had no fertility concerns, according to the Daily Mail, but the couple couldn't find time to "conceive while she was ovulating." The couple, however, has yet to confirm this.

 

Due to their busy work schedules, it's difficult for Priyanka Chopra and Nick Jonas to physically be together to conceive when she's ovulating, so they decided to use a surrogate.  

 

Do you think that's the real reason, or that Priyanka doesn't want to mess with her body by having a baby?
