His actress fiance Genelia D'Souza, whom he is set to marry in Feb 2012, sent out a mushy wish for him on social networking site Twitter.
"Happy birthday to the bestest, most adorable and the sweetest person I have ever known and will ever know, @Riteishd you make life special by just being in it, " posted Genelia, who even congratulated her beau for the news of a 'Legends Walk' that he is planning at Bandra, Mumbai.
According to media reports, Riteish, also an architect, is planning a desi version of the Hollywood Walk Of Fame, with star handprints embedded into the sidewalk -- a project similar to that planned by entertainment channel UTV Stars.
"Congrats @Riteishd on the 'Legends Walk', super sweet thought and because of you, how lucky we are to have all our superstars' handprints embedded into d sidewalk, " wrote Genelia.
Among others who wished the actor a happy and successful life were Karan Johar, Boman Irani, Lara Dutta, Dia Mirza, Arjun Rampal, Farhan Akhtar and Lara Dutta.
