Pippa Middleton will hop on a bike for charity as news reports surrounding boyfriend Nico Jackson become scarce.

In a report from E! News, the 31-year-old will be joining the British Heart Foundation bike ride from London to Brighton this June.

"Middleton, who is currently the ambassador for the charity, is also starring in a new advertising campaign in order to promote the fundraising event," it said.

This year, the annual event-originally launched by Robert Stredder-will turn 40 years old. The cycling event reportedly draws an average of 25,000 cyclists annually and "is now one of the biggest and oldest charity bicycle rides in Europe."

Pippa Middleton seems to take all the rumors about boyfriend Nico Jackson in stride as she focused on her charity works. Back in June last year, she helped raise £15,000 for the Race Across America ride and the proceeds went to the foundation.

In a statement distributed to news outlets during the Race Across America event, Pippa Middleton said, "I was shocked to learn that nearly three times more women die from coronary heart disease than breast cancer. I'm passionate about raising awareness amongst women of this killer disease and I look forward to working with the BHF to highlight to women the risks of heart disease and importantly, how they can reduce them."

The relationship between Pippa Middleton and boyfriend Nico Jackson has not always been smooth.

According to Grazia magazine, as shared by Independent, their busy schedules have been the most pressing issue between Pippa Middleton and boyfriend Nico Jackson.

"Long distance has been tough on them. It's difficult to find time for one another and Nico seems to be getting fed up with it all," the source said.

In the middle of last year, Pippa Middleton's boyfriend reportedly left a job in London to join Jabre Capital as a stockbroker.
