Who are the Bogdanoff twins?
The fraternal twins were once considered French television heart-throbs and were massively popular during the 1980s.
As presenters and producers, they have been the brains behind -- and faces of -- various television shows covering both science and science fiction, after developing an interest in astronomy as children.
Although they were once known for their good looks, the brothers, now 68, are now barely recognisable after each undergoing a several plastic surgery procedures.
Why are they back in the news this week?
Igor Bogdanoff has hit the headlines after being first questioned, and later arrested, for bursting into the home of his ex-girlfriend -- model and biology student, 23-year-old Julie Jardon.
The TV host is accused of forcing his way into the home of Jardon, who then filed a complaint against him.
Grichka Bogdanoff has come out in defense of his twin, explaining in an interview with Closer magazine that he has a passionate temperament.

"He is sometimes too intense when switching from love to friendship. He is a passionate character and sometimes it results in fiery behaviour."
Hasn't there been controversy in the past?
The twins have been involved in several controversies during their years in the spotlight.
The most notable of these, the "Bogdanoff affair" alleged that the brothers wrote nonsensical advanced physics papers that were then published in reputable scientific journals.
The papers, which were alleged by their authors to culminate in a proposed theory for describing what occurred at the Big Bang, were accused of contributing nothing to the study of physics.
The debate that ensued drew considerable coverage in the mainstream media.
So how much plastic surgery have they had?
In 2010 it was reported that the pair were each understood to have a number of chin and cheek implants, as well as botox and fillers.
As a result they have regularly been called "freakish" and described as "cat people" by the media.

Don't they have royal connections?
They certainly have ties with some of Europe's old noble families.
Their grandmother who raised them was a member of the noble Kolowrat family of Bohemia who sent shock waves through European high society by getting pregnant by their grandfather -- the African American tenor Roland Hayes while she was married to another man.
On top of that, Igor was married to both Countess Ludmilla d'Oultremont and Amélie de Bourbon de Parme, the daughter of Prince Michel of Bourbon-Parma.
