Billionaire co-founder of Skype, Janus Friis, is not a happy man at this moment.

The 39-yr-old Skype boss, a few days ago sued his ex-fiancee, a Danish popstar called Aura Dione for refusing to return the $471,000 (over N93 million) engagement ring he had given her when he proposed.

Friis is also demanding that Dione whose real name is Maria Louise Joensen, return the numerous gifts he gave her during their courtship, having claimed that she had “multiple affairs and sexual encounters with other men.”

The expensive engagement ring according to TMZ is said to be “A 1.76 ct round brilliant cut diamond — D color, internally flawless, excellent symmetry and cut grade,” with “a pair of blue pear shaped diamonds of South African origins with a collective weight of .91 ct.”

Reports say that the Skype co-founder is insisting that Dione return a Copenhagen apartment and other presents that were “conditioned upon their marriage.” Friis alleged  that the two were engaged in the summer of 2013, but that Dione “disavowed and abandoned” the engagement by having sex with people who weren’t him.

However, the day Friis filed the lawsuit against his ex-fiancee, Dione posted a tweet on her Twitter page with a Facebook link, referring to traveling with only “a suitcase and a broken heart.”
