Actress Jennifer Garner is not so happy with her husband and actor Ben Affleck's obsession with gambling and hates seeing negative things written about him in the press but has decided to support him.

The 41-year-old was reportedly banned from playing blackjack at the Hard Rock Hotel & Casino in Las Vegas in April after he was caught counting cards.

"She never understood his gambling obsession and she doesn't want him to be in the news (for it), (but) she's the most patient wife ever and is still very much in love with Ben," people.com quoted a source as saying.

Meanwhile, the 42-year-old actress flew to Detroit in Michigan, where Affleck is filming his new movie "Batman vs Superman", this weekend to celebrate their ninth wedding anniversary.

The actor reportedly bought his gorgeous wife some expensive jewellery from Barneys in Beverly Hills last week to mark their wedding anniversary.
