Cara Delevingne has hired a nanny for her pet rabbit.

The 21-year-old supermodel has reportedly sought an extra pair of hands to look after her beloved bunny, Cecil, as the floppy-eared animal is proving more difficult to handle than she expected.

A source told the Daily Star newspaper: ''Cara loves Cecil but he's tiring her out. She never thought a little rabbit would be so much hard work. At the moment she simply has too many commitments to give him the full attention he needs.

''But giving him away is not an option, so she decided an extra pair of hands was the way forward.''

Cara adopted Cecil earlier this year after she posed with the adorable rabbit on a fashion photoshoot.

The stunning starlet has even set up an Instagram account for her prized pet, which has amassed over 100,000 followers.

Cara is said to be so eager to have Cecil by her side at all times she's asked Virgin Media V Festival organisers to create a special area in the Louder Lounge for him to roam free with an all-you-can-eat supply of carrots next month.

Meanwhile, Cara's ex Michelle Rodriguez has been spotted kissing hunky actor Zac Efron on a yacht in Sardinia this week.
