From walking the red carpet together last year to visiting India, Priyanka-Nick made all the headlines for their chemistry, everywhere! Priyanka's and Nick’s whirlwind romance took everyone by surprise and before anyone could fathom what was happening the two lovebirds got officially engaged with a traditional Roka ceremony that took place this morning at PeeCee's house with the presence of the celebrities’ family and friends in attendance.

For the unversed, Priyanka and Nick attended the Met Gala together last year but began dating a few months ago. Nick is believed to have popped the question to Priyanka in London last month on her birthday, with a diamond ring from Tiffany. With family and God, the actress even took to her Instagram account a post to thank everyone for all the wishes and blessings. The NickYanka wedding is reportedly going to take place in October in Los Angeles and we absolutely cannot wait.
