Brandi Glanville insists she was joking when she branded her youngest son ''a complete a**hole.''

The 'Real Housewives of Beverly Hills' star - who caused controversy when she called her seven-year-old son, Jake Cibrian, a ''d**k'' and predicted he would end up in rehab during her podcast show, 'Brandi Glanville Unfiltered', this week - has no plans to apologise.

The 41-year-old star took to Twitter to defend herself today (21.06.14), writing: ''I joke about my kids &dogs being a**holes sometimes cuz honestly they can be but I love them more then life!!people that know me know that! (sic)''

She added: ''OMG I jokingly refer 2my kids&dogs as lil a**holes sometimes cuz they can be. My mom called us her lil- s***ts-stop taking things so seriously (sic).''

Speaking on the podcast, she told actor Jake Lacy: ''My son's name is Jake. He's 7, he's a complete a**hole, but we love him. Oh man, he's a d*ck, seriously.''

She then said that she was ''already, like, booking rehab for Jake down the road'' because of his bad behaviour.

Jake's father Eddie Cibrian, who also has an 11-year-old son, Mason, with Brandi, has yet to comment on the shocking exchange.

The actor and his second wife, Leann Rimes, have been locked in a bitter feud with Brandi since they embarked on an affair on the set of the movie 'Northern Lights' that led to the breakdown of both of their first marriages in 2009.
