Actor Riteish Deshmukh, who so far chose to keep his son away from the limelight, finally shared heart-melting photographs of his son Riaan on social media for the first time.

Riteish's son with Genelia D'Souza was born in November 2014.

The `Masti` actor took to micro-blogging website Twitter to share the three photographs on the occasion of the actor's late father Vilasrao Deshmukh's 70th birth anniversary on Tuesday.

The first photograph shows Riteish carrying Riaan in his arms.

"On my Father's #70thBirthAnniversary Riaan turns 6 months old," the actor tweeted along with the image.

The second photograph featured Riteish, Genelia and Riaan sharing an intimate moment. While Genelia hugs Riteish from behind and kisses him on his head, the `Kyaa Kool Hai Hum` actor is seen cuddling their six-month old.

"Riaan completes us @geneliad," the 36-year-old "Grand Masti" star tweeted.

The third photograph showed Riaan paying respect to former two-time chief minister of Maharashtra and his late grandfather Vilasrao Deshmukh.

"Riaan paying his respects to his grandfather #VilasraoDeshmukh #70thBirthAnniversary," posted Riteish.

The actor married Genelia in 2012.
