The actress and the Coldplay star have been seen in recent days sporting the exact same infinity symbol inking, intertwined with two X's.

The dainty tattoo was noticed on Dakota's left elbow as she stepped out for the Suspiria photocall at 75th Venice International Film Festival last week, while Chris unveiled the same ink on his right forearm in Los Angeles a day prior.

The design was also just about visible on Dakota as she posed up a storm on Suspiria premiere on the red carpet.

The infinity symbol is a popular tattoo design given it's meaning of never ending, limitless love.

The Modern Family guest star and the Texan-born beauty reportedly met through mutual friends, and they were first romantically linked together in October.
