The socialite apparently thinks that the comedian is too immature for her to have a relationship with him, the Daily Star reported.
However, Brand's friend told the publication that the 38-year-old actor is desperate to take things to the next level and make them exclusive.
The source said that the duo do get along great and have a lot in common, but Jemima doesn't think he's mature enough for her to consider a serious relationship, and until he proves otherwise, she has said she can only see him on a casual basis.
Another insider added that Brand is addicted to her, but she's described him as compulsive and obsessive.
