Kate Hudson posed for photos with Lance Armstrong at the weekend, fuelling rumours that they are dating.

Hudson and the cyclist have refused to comment on their relationship in recent weeks, despite media speculation that they are an item.

Armstrong was participating in a charity bike ride to raise $1 million for cancer research.

Before the race, the pair were spotted sharing an embrace at a hotel in Toronto, reports People.

A source said: "He was laughing and she was laughing and they put their arms around each other. It was sweet."

After the race on Saturday, both stars guested at a gala dinner and had their pictures taken with race participants.
