Gwyneth Paltrow wished her "Iron Man" and "Avengers: Infinity War" co-star Robert Downey Jr. a happy birthday on Instagram Wednesday with a selfie that also features "Spider-Man: Homecoming" star Tom Holland.

"I love April 4th because it was the day god gave us @robertdowneyjr HAPPY BIRTHDAY, dear heart. Love me and that other guy in the photo," Paltrow said in reference to Holland who is featured less prominently in the photo.

Paltrow has starred alongside Downey's Iron Man as love interest Pepper Potts throughout the Marvel cinematic universe and will be reprising her role in "Avengers: Infinity War," which is set to hit theaters on April 27.

Downey's Iron Man is also close to Holland's Spider-Man who he began mentoring in "Spider-Man: Homecoming."

The web-slinger has been seen in trailers for Infinity War sporting a new high-tech suit that is presumably given to him by Iron Man.
