Kate Hudson's romantic getaway

Hotting up: Kate Hudson and Lance Armstrong

Kate Hudson and Lance Armstrong might not have publicly confirmed they're dating, but the pair certainly look like they're getting cosier and cosier.

Kate joined her new beau in Canada this weekend for a charity event called Ride with Lance, where 40 residents from Waterloo, Ontario, joined the cyclist on a 117 kilometre ride to raise over $1 million for cancer treatment for two nearby hospitals.

The new couple managed to cram in a mini romantic holiday before the race, too. The outdoorsy pair spent several days in rugged Muskoka, a northern Ontario summer holiday spot where Kate's mum, actress Goldie Hawn, has a cabin.

On Friday Hudson took her son, 4-year-old Ryder, out for ice-cream in the trendy Toronto Yorkville shopping district, where she was also spotted with Armstrong's children, Luke, 8, and 6-year-old twin girls Grace and Isabelle.

Onlookers at their midtown Toronto hotel say the pair look very happy together, after being spotted hugging in the lobby. 'He was laughing and she was laughing and they put their arms around each other,' says one observer. 'It was sweet.'

After Saturday's race, the actress joined Armstrong for a gala dinner at a country estate, and the couple happily posed for photos and chatted with the other participants about their kids and upcoming Father's Day.

One local participant, Tom Wideman, praised Armstrong's 'genuine, down-to-earth' qualities, and added: 'As a cancer survivor, Lance is very committed to take on the cause.'
