Rumer Willis' ex accuses her of deliberately blocking his access to their daughter

Rumer Willis' former partner has accused her of deliberately blocking his access to their three-year-old daughter.

The 37-year-old actress was temporarily awarded primary physical custody of her and ex-boyfriend Derek Richard Thomas' little girl, Louetta, in June, and the musician has filed a legal objection to her recent request to modify their court orders regarding visitation of the little girl.

Derek has asked for June's decision, in which it was agreed neither of them would take Louetta out of California without a valid court order or written agreement, to be upheld and alleged the *House Bunny* actress - who recently moved to Nashville with her daughter - "has done everything in her power to interfere, block and frustrate [his] relationship" with his child.

He added in documents obtained by Us Weekly: "I have had a very close and loving relationship [with our daughter]. At no time have I ever placed our daughter in danger of any kind whatsoever.

"I'm now, and always have been, fully capable of providing Louetta with the care she requires and deserves.

"I reject completely, and without reservation, [Rumer's] claims concerning my alleged abuse of drugs, any conduct on my part that endangers Louetta and any failure at efforts to cooperate with her and coparent."

Derek stated the judge had ordered a six-week period of monitored visits before he could see his daughter alone and have her overnight, but claimed his former partner had "made excuse after excuse that has frustrated my visitation", including "several requests to change the location and scheduled dates and times".

He also claimed Rumer has "treated supervision as something to trade" and allegedly offered to eliminate the need for a monitor in exchange for her choosing someone to accompany Louetta to his upcoming wedding to Lizzie Loch, which is due to take place in October.

He added in the motion: "She has never let me weigh in on her choice of nannies, schools, or doctors for Louetta. Despite our joint legal custody, my views on what is in [her] best interest is not something [Rumer] asks for or takes into account."

He argued Rumer hadn't followed the order that requires them to "confer in good faith and agree in advance" on Louetta's travel plans and school enrolment, and insisted he hadn't consented to their daughter going to Nashville with her mother.

Derek stressed there is a room in his house for Louetta which is "furnished for her, with her own bed, her own clothes, her books and her toys".

He added: "[The] food she likes is always in the house. Everything she needs while she's with me, I provide."

The motion also opposed Rumer's request to reduce his calls to Louetta to three or four times a week for 10 to 15 minutes, which she asked for due to an alleged scheduling issue.

He wrote: "Almost every call ends with [Louetta] not wanting to say goodbye. What has been missing is not my willingness. It is time in person, which has been cancelled, cut short or conditioned on terms the order does not contain."
