Alice Gross' friends are appealing to the public to start taking sefies with yellow #FindAlice ribbons to spread the appeal even further.
A facebook group set up after her disappearance by friends of the Gross family, which now has over 20,000 members, has put out instructions for the yellow ribbon selfies which they hope celebrities will also get involved in.
The admins of the group have said that Alice loves animals so pictures of people's pets wearing the yellow ribbons have also been encouraged.
The group admins have said that the ribbons can be worn in the hair, on clothing, people standing next to a ribbon on a tree or a lamp post or on your pet.
The hope is that the selfies will go viral on Facebook and Twitter and spread the appeal even further.

Detectives carrying out the investigation into the disappearance of Alice Gross have thanked the public for their overwhelming help and support so far.
Over 630 calls have been made to the investigation team since Alice was last seen on 28 August, and additional staff and officers have been drawn in from across the Met to handle the calls into the team.
The search has now reached 24 days. Specialist search trained officers, police dogs and divers have all been mobilised as part of the massive search operation.
Detective Superintendent Carl Mehta, said: "Our thoughts continue to go out to Alice's family as our search continues in a bid to find her.
"I would like to thank the local community who have shown great support to the search effort and police investigation so far. Our officers are working through the weekend - carrying on those searches. We will not stop our hunt for Alice.
"Whilst we have already seized many hundreds of hours of CCTV we still need the public's help. If you are a shop owner, have CCTV at your home, or were out filming in the areas of Ealing and Hanwell and have footage from the afternoon of Thursday 28 August when Alice was last seen, and right up to the 3 September when Arnis Zalkalns was last seen, then please get in touch with us. Save the footage, call into our incident room on 020 8358 0100, or call Crimestoppers anonymously on 0800 555 111."
Officers have so far targeted open spaces, waterways and disused buildings around the route that Alice was known to have taken on the day she was last seen.
This is the largest deployment of search assets mobilised by the Met in support of an ongoing investigation since 7/7. To date the search has involved 600 officers, from eight forces. They have searched 25sq km of open land and 5.5km of canals and rivers.
As the operation progresses, officers are now widening the search area. Detectives are also, similarly, widening their search area for CCTV. So far hundreds of hours of CCTV have been seized and viewed.
