The 24-year-old 'Diamonds' singer, who began dating Brown again in October last year, is keen to spend as much as possible with him, reported Showbizspy.
"Rihanna wants to spend everyday in January with him in 2013 because she thinks that will cement their relationship. She be on that whole sentimental stuff all the time (sic)," a source said.
On January 2, Brown and Rihanna were seen driving through Hollywood, before stopping at a convenience store to grab some food.
"Rihanna showed her dedication to her boyfriend by wearing a shirt from his collection Black Pyramid. It is the second day in the new year and they just want to be posted up together and Chris is cool with that," the source added.
