"Never laugh at your wife's choices. You are one of them. Partners for life!!! #engaged," Zaheer wrote on his twitter handle, after putting up a picture with the 'Chak De! India' actress.
The 38-year-old Zaheer is captaining IPL franchise Delhi Daredevils in the ongoing 10th edition of the cash-rich league.
The two were spotted together at the wedding of Yuvraj Singh and Hazel Keech and the rumours of them dating had been doing the rounds for a while.
The Zaheer-led franchise is currently sixth in the points table with just two wins from six appearances. He has played 95 IPL matches so far and is one short of his 100th wicket.
