Jennifer Aniston and Justin Theroux will reportedly write their own vows for their “romantic” wedding ceremony.
Last week it was reported that the nuptials will take place shortly after Jennifer finishes shooting her latest film this month.
Sources have since come forward to share other plans about the tailor-made ceremony.
"The couple have also designed their own wedding rings with inscriptions inside. And they have written their own vows. It’s going to be very romantic," a source revealed to British magazine Grazia.
Jennifer is rumoured to have picked Valentino to design her wedding dress.
This follows her appearance at this year's Oscars dressed in a gorgeous red Valentino Couture creation. Justin is reportedly set to wear Armani on the big day.
Other details that have emerged include the couple's decision to ban guests bringing wedding gifts. In keeping with the low-key feel of the occasion, Jennifer has not enlisted bridesmaids to help her get ready either.
"Jen and Justin's wedding will be an intimate affair with close friends and family, and Jennifer's ex-husband Brad Pitt is definitely not on the guest list," the source continued.
"They have also requested that instead of gifts, guests donate money to a children's hospice."
The 44-year-old actress is allegedly keen to ensure her nuptials to Justin are very different to when she married Brad in 2000.
Jennifer's elaborate ceremony to the A-list actor took place on a Malibu cliff top, but their marriage ended in 2005.
Sources also revealed that Jennifer will change her surname to Theroux, but only in private.
While the location of their ceremony is being kept under wraps, there is speculation the couple will go all out on three locations for their honeymoon extravaganza.
"Justin has a house in Hawaii, so the island is very special to him, and Mexico is Jen's favourite place in the world," an insider revealed. "Paris is also special to them after they spent a romantic and meaningful holiday there last year."
