This is starting to feel like déjà vu!

Summer may be coming to an end, but things might be just starting to heat up between Chris Evans and Minka Kelly – again – after the on-and-off couple were spotted spending time together over Labor Day weekend.

The Captain America star, 34, and Kelly, 35, took their dogs for a walk together in West Hollywood on Saturday, sparking rumors that they may have rekindled their romance.

Dressed casually and donning baseball caps, the duo seemed to be enjoying each other’s company as they were seen laughing and walking side-by-side on the stroll, even exchanging a friendly high-five at one point.

The two have a long history of breaking up and getting back together. The private couple briefly dated in 2007, and rekindled their romance in 2012. They called it quits in 2013, but they didn’t stay apart for long. Last October the two fueled romance rumors when they were spotted hanging out together at Evans’ home. However, a source told PEOPLE “It was a just a friendly lunch.”

The actors have never publicly discussed their relationship.

Throughout the years, both Evans and Kelly have been linked with other partners. Earlier this summer, Kelly shot down rumors that she was dating Sean Penn, while Evans remained mum about his rumored relationship with Lily Collins.

Evans played coy last week when asked about his love life at the premiere of his latest movie, Before We Go, which is also his directorial debut.

“Oh god, I couldn’t even think about my own life,” Evans said when asked if he’s ready to settle down. “I had no life during this movie. This movie was all about the movie and that was it.”
