Reese Witherspoon loves ''spending alone time'' with husband Jim Toth.

The 'Wild' actress, who has 15-year-old daughter Ava and 12-year-old son Deacon with ex-husband Ryan Phillippe and two-year-old son Tennessee with the 45-year-old talent agent, recently enjoyed a romantic holiday to Massachusetts' Nantucket Island and is reportedly making plans to have another baby with her beau.

A source close to the couple, who got married in 2011, said: ''They'd love to have another baby.''

The duo enjoyed some quality time together with friends last weekend, where ''they were super affectionate''.

The insider told US Weekly: ''Reese was excited for this trip and spending alone time with Jim.

''It was a group of couples enjoying sunsets and cruising around the island.''

The 39-year-old Oscar winner recently insisted it is impossible for anyone to get their family and career balance ''perfect''.

She said: ''No one's really doing it perfectly. I think you love your kids with your whole heart, and you do the best you possibly can.

''But, you know, right now I'm feeling sad missing my little 2-year-old, and my daughter's about to finish her freshman year of high school, and my son has a golf tournament this weekend that I hope I don't miss.''
