Channing Tatum's comment on Lenny Kravitz's photo did not go unnoticed. Channing Tatum and Lenny's daughter, Zoë Kravitz, have been linked romantically for several months.

It seems the two have kept their relationship so off the radar that fans may have forgotten about them. Let me remind you that things seem to be heating up between these Hollywood celebs.

Channing and Zoë have a serious connection and are definitely more than just colleagues.

"They spent the weekend in N.Y.C., strolled around the city, met up with friends, and visited the Guggenheim Museum," a source said. "They looked very happy. They have this cute and flirty chemistry." The insider added, "Zoë thinks Channing has depth both as an actor and a person." Another source told the outlet, "Channing likes that she is independent and outspoken as well as bright."

The two are currently working on Zoë's first project together that she created. Channing will be the male lead of her debut directing film, Pussy Island.

"Channing Tatum and Zoë Kravitz fuel dating rumors with NYC bike ride."

"Zoe Kravitz and Channing Tatum were photographed inside the #MetGala together after walking the red carpet separately."

Whether they were trying to hide it or not they did a terrible job at concealing their relationship. Even though the pair haven't officially confirmed the speculation, the dots are all connected.

"2:37pm. Good morning. All nighter in the studio last night. 3 albums on the horizon. Going back in. Love."

The Magic Mike star commented, "Good god man! What are you eating or what’s in the water or the genes. It’s not natural. Do you just do abs like all day?"

Lenny responded, "Dude, I'm just trying to get into the next Magic Mike," and hilariously added, "Any connections?"

It seems Channing and Lenny have a solid banter which can only mean one thing... he and Zoë must be pretty serious.
