Guess which starlet is walking down the aisle for the third time?

Hint: she has two children and so does the man she's marrying....

Uma Thurman said yes to a proposal from Swiss financier Arpad "Arki" Busson and is said to be wearing an "amazing" engagment ring (eight-plus carat centre stone surrounded by 20 smaller stones). Sounds lovely!

Uma was previously married to actors Gary Oldman, then Ethan Hawke, the latter of which she has two children with.

Arki is no stranger to high-profile weddings either.  He has two children with former girlfriend Elle MacPherson.
