Tennis player David Ferrer is competing in the Samsung-sponsored Mutua Madrid Open this weekend.

The tweet was sent from his iPhone.

The snafu is an increasingly common mistake from celebrities who endorse tech products. Singer Alicia Keys, BlackBerry’s new creative director, was caught tweeting from her iPhone a few months ago. Keys claimed she was hacked and deleted the tweet.
Last year, Oprah Winfrey used her iPad to tweet about how much she loved Microsoft’s new Surface tablet.
