He may be the star of the "Die Hard" films, but Bruce Willis is a softie when it comes to his wife.

On Monday, the 57-year-old actor gave fans and paps an eyeful at the Berlin premiere of his new film, "A Good Day to Die Hard," when he planted a big wet one on Emma Heming, his wife of four years.

Their PDA came four days after Willis attended the unveiling of a "Die Hard" mural -- a portrait of Willis's character in the original 1988 film -- at Fox Studios in Los Angeles to commemorate the 25th anniversary of the franchise. "A Good Day to Die Hard" is the series's fifth installment; in John McClane (Willis) travels to Russia to help out his son, a CIA operative.

According to USA Today, Willis hit a "detonate" button to unveil the mural from beneath a curtain, which caused fireworks to explode and cheers to erupt from the audience. His daughters Rumer and Tallulah Belle looked on proudly as their dad talked about what a "great ride" the films have been.

"I just couldn't be more pleased that you all came out here to help honour me," said Willis on Thursday. "It has been a big fun time doing 'Die Hard' for the last 25 years and living to talk about it."

The combined films have reportedly made more than $1.1 billion worldwide -- no wonder Willis is so frisky!
