Prince Harry refused to answer questions about his girlfriend Cressida Bonas and the rumors that have surrounded them about a possible engagement soon.

Prince Harry was asked multiple questions about his girlfriend Cressida Bonas and when they will get engaged, at a fundraising dinner in Dubai last night for his Sentebale charity, which raised more than $1 million to support vulnerable children in southern Africa, Express reports.

According to the report, Prince Harry mingled with the rich and famous at the fundraising dinner in Dubai, but deliberately laughed off questions about a possible engagement and marriage to girlfriend Cressida Bonas, according to Express.

The 29-year-old Prince and Cressie, 24, a dancer, have been dating for more than 18 months.

Friends have described their relationship as serious and said they could see them getting married.

Harry and Cressida were rarely seen in public, but this weekend they were spotted on back-to-back dates. First they went to an intimate gig by James Blunt, then went to watch the musical "The Book of Mormon."

According to Express, Harry and Cressida avoided the public eye because Prince Harry was afraid the media would scare Cressida away. Perhaps now their relationship is strong enough to take the pressure.

Prince Harry stopped in Dubai on his way back from an official visit to Australia over the weekend.

According to Express, Sentebale, which helps children with HIV/ AIDS, agreed to work in partnership with the Al Jalila Foundation, a global philanthropic organization established by Sheikh Mohammed Bin Rashid Al Maktoum, Vice-President and Prime Minister of the United Arab Emirates and Ruler of Dubai.

The agreement with Sentebale is its first international partnership and was launched last night at the JW Marriott Marquis Hotel in Dubai.
