Britain's fifth in line Prince Harry faces off with former U.S. President Barack Obama in a radio show interview for BBC. The interview is part of the prince's guest editor stint for the radio station.

The Royal Family recently released a teaser of what to expect from the interview, showing what went down in the pre-talk briefing between the two.

Prince Harry and Mr. Obama's bromance was on full show in the short clip, which the former president kicks off by asking if he needs to have a British accent for the interview. The prince quickly answered, "not at all."

Prince Harry, however, reminded his guest to answer quickly, unless he wants to get "the face." Mr. Obama then joked for the British royalty to show the face, which turned out to be a mock-stern look from Prince Harry.

"I don't want to see that face," said the former president while grinning.

While the prince was excited about the interview, he was also undeniably nervous. Mr. Obama then kindly offered, "I'll interview you if you want."

Prince Harry laughingly answered, "No, no, let's keep it this way. I much prefer that."

According to Kensington Palace, the actual interview will talk about his memories from the day he left the Oval Office, his hopes for his life after presidency and his future plans, particularly for the Obama Foundation.

Their discussion was recorded at September's Invictus Games in Toronto and will be broadcasted on Dec. 27 on BBC Radio 4's Today program.

Prince Harry and former President Obama have been friends for a number of years, and have been photographed sharing good times together several times in the past. Prior to the Invictus Games, which they both attended, the two parties had a funny social media war over Twitter, which also enlisted former first lady Michelle Obama and Queen Elizabeth II.
