Lindsay Lohan wants to be pregnant by the ''end of the year''.

The 'Mean Girls' star is reportedly keen on starting a family and is ''rushing head first'' into planning a pregnancy.

A source said: ''She's been telling people she'll be pregnant by the end of the year. She's rushing head first into this.''

The news that the 28-year-old actress - who is dating Mathia Milani - wants to have a baby has shocked her pals, who think she is ''crazy'' to consider having a baby right now.

The source added to US' OK! magazine: ''It's crazy, because only a few weeks ago Lindsay was drawing up lists of guys to date.

''Most people are convinced this romance with Mathia is nothing more than a fling.''

Meanwhile, Lindsay recently vowed to make a ''fresh start'' with her ''clean slate''.

Speaking after she completed her community service for a reckless driving incident, which took place in 2012, she said: ''I am very grateful to those at Brooklyn Community Services, Duffield and The Ali Forney Center for welcoming me into their services and allowing me to finish my court ordered Community Service hours.

''Thank you to Shawn [Holley, lawyer] and everyone involved for having faith in me and supporting me in getting the job done.

''I look forward to working with The Ali Forney Center and BCS in the future. Thank you for the inspiration. Clean slate. Fresh start. Bless.''
