Christina Aguilera was ready to put her drunken arrest behind her and get back to work last night as she started filming her new music video.

The singer was spotted leaving Smashbox Studios in Hollywood in a little black robe and jumped into a limousine to head home, which marked her first public appearance since being arrested early Tuesday morning.

Despite her bad start to the year, the 30-year-old singer had a cheeky grin on her face as she slipped out of the studio.

But not even Christina’s heavily piled on fake tan and mahogany lipstick could disguise the trouble in the singer’s personal life.

The mother-of-one faced an embarrassing arrest for public intoxication earlier this week, because she ‘was not capable of taking care of herself’.

Her arrest came amidst U.S. media reports saying the star’s friends have been encouraging her to enter rehab for some time.

Since her marriage breakdown last year, Aguilera has been under a noticeable about of strain and after a disastrous Super Bowl performance in February, where she mixed up the words to the National Anthem, and collapsing on stage at the Grammy Awards, fears for her health have only escalated.

But the Burlesque actress is trying to put her troubles in the background while she gets her mind back on her career.

Christina has signed a deal with NBC to appear in a new reality television show called The Voice, which aims to find musical talent.

She will join rapper and record producer Cee Lo Green and Maroon 5’s Adam Levine as a music coach on the show.

The Dirrty singer expressed her joy about the new show, saying: ‘I am so excited to be part of such a wonderful project that celebrates music and the talent behind it.

‘To be given the opportunity to help shape new artists’ careers and mentor them to see their dreams come to fruition is a task I welcome with open arms.’

Perhaps the star was celebrating her new TV role the night she was arrested for public intoxication, which saw her being taken in by police at around 2:45am on Tuesday.

Her boyfriend Matthew Rutler was also arrested for driving under the influence in Los Angeles but left jail on a $30,000 bail.

Aguilera was Rutler’s passenger and the couple were pulled over when police caught the 25-year-old driving dangerously.

Steve Whitmore, the chief public information officer for the Los Angeles Sheriffs department said of the recent arrest: ‘The [police] witnessed a person driving erratically.

‘At 2:45am this morning a gentleman was stopped for allegedly driving under the influence. He was subsequently arrested and his passenger, Ms Aguilera, she was arrested.’
