Oprah Winfrey made $12 million from just one tweet, focusing solely on eating bread.
The media mogul is a shareholder in Weight Watchers and she posted a short video message about being able to lose 26 pounds, while still eating bread recently.
Shortly after the post went live, shares in the weight loss brand - of which Oprah owns $6 million, making her the largest individual stakeholder - increased by 18 per cent, or around $2.10 per share, within an hour, according to Market Watch.
The multi-million dollar tweet posted on Tuesday shared a video link alongside a message which read: "Eat bread. Lose weight. Whaaatttt? #ComeJoinMe (sic)"

In the 30-second clip, Oprah said: "I lost 26 pounds, and I have eaten bread every single day."
However, the 61-year-old star won't be able to bank her profits just yet as she would have to sell her shares to get the funds.
Oprah became a spokesperson for Weight Watchers in October, just after buying 10 per cent of the organization’s shares for around $43.2 million, and follows in the footsteps of the likes of Jennifer Hudson and Jenny McCarthy who have previously represented the group.
This followed an emotional message on Twitter from the star, as she left fans in tears with her weight loss story recently.
