Actress Parineeti Chopra is proud of her star cousin Priyanka Chopra, whom she has described as hardest worker and a loving sister.

Parineeti expressed her love for the "Dostana" star, who turned a year older on Monday, by taking the virtual route.

"The hardest worker and a loving sister who keeps us in check! Proud of what you have achieved. No one deserves it more than you! Priyanka Chopra," tweeted Parineeti.

It's not the first time that Parineeti has praised her sister in public. She recently said it would be "wonderful" if gets an opportunity to sing with her cousin, who has sung foot tapping numbers like `In My City`, `Exotic`, and even the title track of `Dil Dhadakne Do`.
