Rumors are flying that the couple, who has been dating for about 19 months, will attend a private dinner at Sandringham that Prince Harry is supposedly throwing Friday night.
According to the Sun, the 29-year-old prince's "informal" party will take place at the Queen's Norfolk estate, with his cousins princesses Beatrice and Eugenie set to attend, as well as his 24-year-old model girlfriend.
The Daily Mail reported, however, that there is no truth to those rumors, saying Bonas won't be going to Sandringham in spite of reports that suggested otherwise.
The palace had no comment on those reports.
Meanwhile, although the redheaded royal and his ladylove spent Christmas apart with their families, the duo will reportedly be ringing in 2014 together, according to the Daily Mail.
Prince Harry is set leave the royal family's festivities to reunite with Bonas just in time to celebrate the New Year.
After the New Year hits, Prince Harry may spend a few days skiing before returning to his Apache helicopter pilot duties.
