Congratulations to Robert Downey Jr. and his wife Susan!

The couple welcomed their first child together in LA on Tuesday morning, People reports. Weighing in at 7 lbs., 5 oz., and at 20 inches long, RDJ and wife named the bundle of joy Exton Elias. This is the second son for the Sherlock Holmes star, as he has an 18-year-old, Indio, from a previous marriage.

With a name like Exton, RDJ wouldn’t be the only celeb to name his baby something unique! From Beyonce and Jay-Z’s newborn daughter Blue Ivy to Kate Hudson and Matthew Bellamy’s son Bingham, check out other odd celebrity baby names in the gallery!

So what’s the meaning behind Exton’s name?

According to CuteBabyName.com, the name comes from the Shakespearean time and refers to ‘King Richard The Second’ Sir Pierce of Exton. Wonder if the Iron Man knew that when naming his new son?
