Picking up where Chris Hemsworth, 32, and Liam Hemsworth, 26, left off, the oldest Hemsworth, Luke, 35, recently joined in on the faux Instagram feud raging between his famous brothers.

Luke entered the ring on Tuesday by sharing a photo that shows the Chris and a group of friends enjoying a few beers in the sun. The group pic is hijacked, however, by the actor's bulging muscles glistening in the sunlight.

"Hey @chrishemsworth do you even lift bro? @lukemun @emerysurfboards" Luke chided his brother in the caption. Obviously that was a rhetorical question.

The bro battle actually began back in October when Liam posted an Instagram photo of his dog Tani chewing on a Thor action figure. "Tani's favorite chew toy #Thorsday" he captioned the photo of the mangled doll in the dog's mouth:

Chris responded by scribbling on Liam's December cover of Men's Health, and sharing a photo of his artwork on Instagram:

Liam fired back a few days later by posting a photo of Chris's December cover of Vanity Fair, which he doctored with red marker.

"Really great cover bro! @chrishemsworth," he wrote alongside the pic of his handiwork.

Liam's retaliation seemed to have ended the sparring, that is, until Luke recently joined in. Keep it comin' boys!
