Like her famous father, her love life has certainly been colourful and includes two broken engagements.
She became engaged to Whitestarr rocker Cisco Adler in early 2005 after a year-long romance, however they split May that same year.
During the relationship, she got a tattoo that read 'Daddy’s Little Girl Loves Cisco' on her right hip and described him as her 'best friend, lover and soul mate'.
After their breakup, she quickly changed her ink to say, 'Daddy’s Little Girl Loves Disco.' Adler went on to date The OC's MIscha Barton.
In November 2005, reality TV star Talan Torriero, who was then starring in Laguna Beach, proposed to her after a brief romance.
They called of the engagement 11 days later.
'It is better to have a brief engagement than a short marriage,' a spokesperson said at the time.
She also counts Girls Gone Wild creator Joe Francis as an ex boyfriend and was rumoured to have dated Jack Osbourne.
She famously gave Sharon and Ozzy's son her D-cup silicone implants as a gift after she had them removed. He had them framed and now hangs them on his bathroom wall.
In 2008, Kimberly was caught passionately kissing British actor Jude Law at an Essex nightclub and that same year she dated Welsh star Rhys Ifans. Both actors had previously dated Sienna Miller.
Toro, who won an Academy Award for his 2001 role in Traffic, has had his share of high-profile lovers.
He has previously been linked to a string of actress including Alicia Silverstone, Scarlett Johansson and Minnie Driver.
He also enjoyed romances with Greek-Italian screen star Valeria Golino and British actress Claire Forlani.
While promoting his film The Wolfman last year, he described his romantic life as 'in limbo'.
When asked if he had thoughts of settling down, he responded indignantly by saying: 'Why? Everyone says, "Why isn’t he married?" But it’s like, ‘F***! Why do I have to get married? Just so I can get divorced?'
The Che and 21 Grams star made it clear in his interview with The Times that he didn't want his West Hollywood apartment, which he described as his 'cave', to be 'invaded' by a wife and children.
Kimberly is Rod's daughter from his marriage to Alana Hamilton.
The rocker is now a father of eight - his wife Penny Lancaster gave birth to a baby boy, Aiden, in February.
It will be his first grandchild.
