The 46-year-old "Cake" actress has shunned the services of a professional wedding planner and has instead asked Dimitri Dimitrov from Los Angeles' Sunset Tower Hotel to help arrange her nuptials, reported Femalefirst.
"Jen has spent so much time at Sunset Tower over the years that she and Dimitri have become close friends. He personally escorts her in and out of a back entrance so she is never hounded by the paparazzi," a source said.
"Jen has put him in charge of the flowers and linens - anything that will make the party flow. Obviously he is running everything by her but she's relying on his expertise - and, most importantly, the fact he'll be discreet," it added.
