Benji Madden is not convinced the wedding to Cameron Diaz is enough to show his commitment, as the former Good Charlotte guitarist had his wife's name tattooed across his chest.

The rocker posted on Instagram a photo of Cameron Diaz's name tattooed across his chest. Benji Madden captioned the image: "Thinking bout you❤️❤️❤️ #LuckyMan."

Cameron Diaz has not responded to her husband's sweet Instagram message, however.

"Hopefully Benji doesn't join Johnny Depp, Heidi Klum, Angelina Jolie, Adrienne Bailon and Nick Cannon, who either removed or covered up tattoos of their ex-loves," OK! magazine noted.

"So what's next for the couple?" the tabloid added. "A baby could be on the way, as the duo was spotted shopping at a baby boutique soon after the wedding."

A source told the tabloid that neither Benji Madden nor Cameron Diaz wants "to waste any time" by expanding their family.

The couple celebrated their wedding at her mansion on Jan. 5. Nicole Richie (who's married to Benji Madden's twin brother Joel), Drew Barrymore, and Cameron Diaz's older sister Chimene Cain were the bridesmaids in the wedding. The former Good Charlotte guitarist also gave the "Sex Tape" actress a note before the vows.

The bridesmaids all wore black dresses as they entered the room with Ryan Adams' song playing in the background. The ring bearer for the wedding was Sparrow Madden, the 5-year-old son of Nicole and Joel.

Their wedding, however, received some criticism for reportedly trivializing the Jewish tradition since the neither of the couple is Jewish.

In recent days, Benji Madden and Cameron Diaz have been snapped doing groceries, dining out with friends and doing what regular couples do.

Heat World commented that although Benji Madden is riddled with ink, it's hard to miss the name "Cameron" across his chest because "it's pretty big."
