Hrithik Roshan and rumoured girlfriend Saba Azad frequently feature on the trends list for their relationship. Well, the reason we brought this up is because they just made their relationship red carpet official at Karan Johar's 50th birthday bash held at the Yash Raj Studios in Mumbai on Wednesday night. Both Hrithik Roshan and Saba Azad were seen twinning in black outfits as they walked towards the venue together. Both Hrithik and Saba happily posed together for the cameras at the bash.
