It's official, Showtime's "Sinful Sundays" are a big hit. Following increases in rating and acclaim, Showtime has opted to renew its Sunday triumvirate of 'Shameless,' 'House of Lies' and 'Californication' for additional seasons to begin airing in 2014. The move comes as something of a surprise for 'Californication' at least, thought to be on its last legs and debating the possibility of a spin-off featuring Maggie Grace's character "Faith." Find out what Showtime has to say about the renewals inside!

'Shameless,' 'House of Lies' and 'Californication' fans can officially rest easy, their sinful Sunday heroes will all return in 2014. Today Showtime president David Nevins announced the renewals, granting a fourth season to 'Shameless,' a third to recent Golden Globe winner 'House of Lies,' and a surprising seventh to the David Duchovny-fronted 'Californication.' Says Nevins:

'Californication,' 'House of Lies,' and 'Shameless' possess highly distinctive comedic voices, and given that all three continue to grow their audience season after season – the pick-up decision was easy. I am incredibly excited to see what each of these series has in store for their next seasons.

All three series returned on January 13 with their highest-rated episodes ever, averaging 5.4 million viewers per week for 'Shameless,' 3.2 million for 'House of Lies,' and 3.1 million for 'Californication.' The three series will begin production on the new seasons later this year.
