Slovak former pornographic actress Karma (Karma Rosenberg ) was born on 3 January 1981 in Zvolen, Czechoslovakia [now Slovak Republic]. She is an actress and director.Karma first appeared in a casting video directed by Pierre Woodman for Private. This appearance dates back to late 1998 or early 1999. After that, she continued to make herself known thanks to films made with Rocco Siffredi, including two of the hardest films directed by Rocco: True Anal Stories 6 and Dirty Anal Kelly in Rome 2 Among Karma's other early films, there is True Anal Stories 11 and the Christophe Clark film Hardball 7.

Karma has also filmed scenes for various Private studio films such as Matador 12: Avalanche and Matador 4: Anal Garden. Between the end of 1999 and the beginning of 2000, she had her right forearm tattooed, her figure became slimmer and slightly muscular. She also began to wear makeup during this period. With her very dark hair and her physical presence due to her large size and musculature, Karma often plays dominatrix roles, notably in German films like Sex Hexen in which she is the leader of a pagan group of Amazons.

While filming gonzo films with Nacho Vidal, she expressed the wish to have "bigger" breasts. Which she did in 2002-2003, the operation giving her breasts that looked rounder and firmer.

Recently she has been appearing on many gonzo websites, shooting various scenes for the owners Bang Bros (who also own Eurobridetryouts, Asstrafic, Allinternal, etc.). Since the end of 2004, his appearances have become increasingly rare. Some speculated that his career might end because Karma wanted to start a family in the United States.

Little is known about her. She is Slovak, although it is often (incorrectly) stated that she is Romanian, Ukrainian or Czech. We find her under the following pseudonyms: Karma, Karma Nera, Karmen Solana, Lulu Fontaine, Renata, Carmen Rosenberg and Karma Rosenberg. It is likely that her most common pseudonym, Karma Rosenberg, refers to the historic aristocratic "Rosenberg" (Rožmberk) family who are very famous in the Bohemia region.
