Lionel Richie made a rare red carpet appearance alongside his adopted daughter Nicole, her husband Joel Madden and her look-alike kids.

The family stepped out at the premiere of Nicole's latest flick Don't Tell Mom the Babysitter's. The actress, 42, and musician – brother of Benji Madden, who is married to Cameron Diaz – were joined by their daughter Harlow, 16, and son Sparrow, 14.

Held at The Grove in Los Angeles, the brood smiles for snaps as they came together to celebrate the new release. Lionel, 74, also brought along girlfriend Lisa Parigi and ex-wife Brenda Harvey-Richie. Lionel and Brenda, who tied the knot in 1975 before their subsequent divorce in 1993, adopted Nicole when she was just nine back in 1990.

Daughter, Harlow Winter Kate, was born in January 2008, followed by son, Sparrow James Midnight, who was born in September 2009. Nicole and Joel tied the knot in December 2010 in a French garden themed wedding on adopted father Lionel's estate. The nuptials reportedly included 155 a guests and a live elephant.

Nicole was born in Berkeley, California on 21 September 1980. Her biological parents are Karen Moss, who was then a backstage assistant for Lionel, and her musician partner Peter Escovedo, a member of Lionel’s band. The couple were having difficulties, so Lionel and his wife Brenda offered to look after Nicole on a temporary basis.

Recalling the moment he first met Nicole – who was playing tambourine on stage at a Prince concert in 1983 - Lionel said: "I thought, 'Oh my God, what a cute little button'." Six years later, the Richies' officially adopted Nicole and she took their name.

But Nicole was crushed at the age of 10 when dad Lionel left Brenda for another woman and went on to have two more kids – Sofia Richie and Miles Brockman, who are both models. As the daughter of a world-famous star, Nicole grew up in the spotlight and was a regular on the showbiz circuit. In her teenage years she admitted to falling in with the wrong crowd, who introduced her to hard drugs.

At the age of 14 she was doing cocaine and by 19 had moved on to heroin. Substance abuse offered an escape from the emotional pain she had been suffered. "I went into drugs so I wouldn’t have to deal with it," she previously told Vanity Fair.

In 2003, Nicole made her TV debut on The Simple Life with then best friend Paris Hilton. One of the first big reality shows of the Noughties, cameras followed the wealthy socialites as they left their privileged lives behind to travel across America working a series of ‘real jobs’. Their antics included milking cows on a dairy farm, working a fast food drive-thru and looking after kids in a day care centre.
