Gwyneth Paltrow posts rare photo with boyfriend Brad Falchuk

March 2 (UPI) -- Gwyneth Paltrow wished "handsome" boyfriend Brad Falchuk a happy birthday Wednesday.

The 44-year-old actress shared a rare photo with the Glee and American Horror Story co-creator on his 45th birthday.

"Happy birthday, handsome," she captioned the picture for her 3 million Instagram followers.

Paltrow and Falchuk were first linked in 2014 after meeting on the set of Glee in 2010. The couple keep their relationship private, although Paltrow did include Falchuk in another post on Thanksgiving in November.

"I could not be more grateful for these people and those not pictured who bring love and laughs and heart to my life," she wrote at the time.

Paltrow was previously married to Coldplay frontman Chris Martin, and shares 12-year-old daughter Apple and 10-year-old son Moses with the English singer. The pair split in 2014, but have remained close since their divorce.

"He's at my house every single day," the actress said in the Feb. issue of InStyle. "We have our own lives but we still have our family life."

"To this day, Chris would take a bullet for me, even though I'm not his wife," she added. "I honestly think Chris and I have contributed something positive to the culture of divorce."

Paltrow will next star in the movie 33 dias about Pablo Picasso. Falchuk is also known for co-creating the series Scream Queens and executive producing American Crime Story: The People v. O.J. Simpson.
