Arnold Schwarzenegger and heavyweight champion Wladimir Klitschko have exchanged a series of shirtless selfies on Twitter.

The 66-year-old former governor of California then revealed to his followers on Twitter that after exchanging selfies, he and Klitschko met up for dinner.
“After the Twitter pose-down, I met up w/ @Klitschko for dinner @stanglwirt. Thanks to our great host Maria Hauser,” he wrote, posting a picture of himself with Klitschko, who is dating Nashville’s Hayden Panettiere, and their host.

Daily Mail notes the boxer, 37, first dated Panettiere, 23, from 2009 to 2011. They then reunited back in January, and Panettiere has since surfaced wearing a diamond ring on her wedding finger. The couple has yet to confirm reports that they are engaged, though.
