AceShowbiz - %cNaomi Watts% is making it official with new boyfriend %cBilly Crudup%. The 49-year-old actress and her "Gypsy" co-star Billy, also 49, appeared to go public with their romance as they were photographed holding hands while leaving a 2018 BAFTAs after-party in London, England, on Sunday night, February 18.
The lovebirds, who portrayed husband and wife on the Netflix show, first sparked dating rumors last July. Following Sunday's award-giving ceremony, the couple hit the Vogue after-party at celeb hot spot Annabels, where Naomi opted for an all-black ensemble in support of the Time's Up movement, while her new beau went tie-less in a white shirt and gray suit.

The two got close while filming "Gypsy". A source confirmed to PEOPLE mid-last year that the pair were "dating" in real life. An eyewitness also told Page Six that the couple was spotted holding hands in New York City last year, and another eyewitness said that they "looked happy and were laughing a lot, then left again holding hands."
"We didn't know they were a couple. Pretty cool seeing two big stars so into each other," the source said. Neither Naomi nor Billy publicly confirmed the dating report at the time.
Naomi split from %cLiev Schreiber% in September 2016. In a joint statement the duo said, "Over the past few months we've come to the conclusion that the best way forward for us as a family is to separate as a couple." They continued, "It is with great love, respect and friendship in our hearts that we look forward to raising our children together and exploring this new phase of our relationship."
The two had been together for 11 years and share two children, Alexander, 10, and Samuel, 9. While Naomi has been linked to Billy, who has a 14-year-old son, William, from a previous relationship with actress %cMary-Louise Parker%, and has also dated %cClaire Danes%, Liev, 50, is rumored to be dating Miss South Dakota, 26-year-old Taylor Niesen.
