Mumbai: Actor Riteish Deshmukh described his wife and actress Genelia Deshmukh as his best friend, lifeline and strength on her 31st birthday on Sunday.

"Serendipity: Friendship Day meets birthday. Wishing my bestest friend, my strength, my lifeline, my 'Baiko' a very happy birthday. Loads of surprises in store before the day ends. Love you Genelia! And yes, every birthday you don't need to remind me that you are way younger than me!" Riteish, 39, tweeted on Sunday.
