It looks like Prince Harry and girlfriend Cressida Bonas have already taken their romance to the next level and started playing house. A source recently revealed that the attractive couple's romance is stronger than ever.

According to E! News, an insider revealed that the private couple has been enjoying their time together. The source said, "Harry and Cress are just a great fit-she just fits into his life, with his friends. It's all been really easy."

Prince William's little brother, 29, and Bonas, 25 have been dating for some time and many are anticipating a royal engagement announcement.

The insider revealed, "They spend loads of time together, she has a load of stuff at his place and they're really relaxed and comfortable."

As of lately Prince Harry has become more comfortable with going out in public with his girlfriend who he met through his cousin Princess Eugenie back in 2012.

Back in March Cressida Bonas attended her first official royal event with her boyfriend which featured Harry speaking to 12,000 young people.

However, despite how in love the couple may be, they have continued to keep quiet about their future. An insider admitted, "They are clearly crazy about each other and privately his friends are sure it's going to last, but they're super private about that question," adding, "Friends know better than to ask."

Last month, a friend close to the couple revealed that they "made a point of talking about marriage and what changes they're going to have to make to their life," if and when a marriage proposal should happen.

The source continued, "Up until now Cressida has loved the fact they can have a lot of freedom in public," adding, "But they are fully aware once they decide to proceed to marriage things will get a little crazy and the attention on them will increase."
