Selena Gomez, Robert Downey Jr. all smiles as they hit the 'Dolittle' premiere together

Selena Gomez knows how to wow not just her fans but leaves even the biggest stars charmed by her personality. 

The 27-year-old Lose You To Love Me singer was spotted rubbing shoulders with Robert Downey Jr. at the premiere of their freshly-released film Dolittle.

The diva seems to be kicking off the new year on a celebratory note as she goes around spreading positive vibes and winning hearts of whoever she comes across and adding many feathers to her caps.

Selena had lent her vocals for the character of Betsy the Giraffe for the film while the Avengers: Endgame actor took the lead role of Dr. John Dolittle in the Stephan Gaghan-directorial.

Selena was a sight to behold as she rocked a Givenchy couture gown with gorgeous diamond drop earrings paired with a moon ring designed by Paris-based Messika.

On the other hand, Downey, who embodies Iron Man in the famous Marvel films, was looking dapper in a navy patterned shirt finishing the look with a velour jacket.
