Taylor Swift and Calvin Harris are rumored to be excited about the chance to make up for lost time.

With Swift's 1989 World Tour now officially behind her, Hollywood Life is reporting the two wide-eyed lovers are planning to spend at least the next several days lounging around in no one's company but each other's.

"Calvin and Taylor have hardly seen each other since she began her '1989 World Tour,' so they want to make up for lost time," a source said.

Making the occasion even more special is the fact the "Shake It Off" singer just celebrated her 26th birthday. With Swift reported to still be working her way back to the states, celebratory plans for the day are rumored to still be a work in progress.

All that seems clear is that Swift is looking forward to spending as much time with her 31-year-old boyfriend as she can.

"That's actually being played by ear," a source added of a possible birthday celebration.

"Calvin was thinking of getting a little get-together with her friends in LA, but that's all dependent on how she feels after a long flight back from Australia. But, the two do want to spend the next week in bed together because they've really missed being a couple, and really missed their intimacy with one another."

Besides it being her birthday, Swift's reasons to having to celebrate seem endless.

Her 1989 World tour Live will be streaming on Apple Music starting Dec. 20, and she was just nominated for seven 2015 Grammy Awards.

According to Variety, Swift's nominations include album of the year for "1989" and song of the year for "Blank Space."

Besides ranking as the fastest album ever to sell at least five million units, "1989" also became just the fifth album to rank in the Top 10 in album sales for an entire year.
