Uma Thurman finds herself in the middle of a court battle with ex-fiancé Arpad Busson after he filed an emergency order seeking custody of the couple’s two-year-old daughter.

The pair welcomed Rosalind Arusha Arkadina Altalune Florence Thurman-Busson, reportedly nicknamed Luna, in July 2012 after dating on and off for five years. They ended their second engagement in April of 2014.

The papers submitted by the French financier in Manhattan Supreme Court are currently sealed so it is unknown where the filing stands.

Although Arpad has not commented on the reports, a spokesperson for Uma told ET, "It is unfortunate that this very private discussion regarding Mr. Busson’s visitation rights and his participation in decision making has been made public. However, we are optimistic that a fair agreement for both sides will be reached out of court."

In addition to Luna, Uma has a 16-year-old daughter and 12-year-old son from her previous marriage to Ethan Hawke. Arpad is the father of two sons with Australian supermodel Elle Macpherson.

ET was the first to release a statement from the actress’ rep.
