Almost two years having been rumored together, Katie Holmes and Jamie Foxx haven't opened up their relationship yet. A source, however, told Us Weekly that their relationship was getting serious as there was L-word in their conversation.

Katie was caught saying the L-word on a phone conversation with Jamie after landing at L.A.'s LAX Airport. "She said she loved him. She always gushes about how amazing he is and the joy he brings into the world," the source said. On the other hand, Jamie reportedly called her "my girl" in front of his pals.

The rumor about the two dating started to emerge in 2013 when Katie was seen dancing with the Oscar winner at a party in East Hampton, New York. In March, Us Weekly published a photo of the two holding hands in a studio, showing how intimate the two were. A source said that the "Dawson's Creek" star got everything which she didn't get from Tom Cruise with Jamie. "Jamie is someone she can trust and have fun with," the source said.

The 36-year-old actress knew Jamie through Tom when they worked on a 2004 film, "Collateral". She split from the "Edge Of Tomorrow" star in 2012, after five years of marriage. The actress moved to L.A. earlier this year allegedly to get closer to Jamie.
