Justin Timberlake spent his first Father's Day (21.06.15) at a luxury Canadian retreat.

The 'Mirrors' hitmaker - who was accompanied on the trip by his wife Jessica Biel and two-month-old son Silas - booked a penthouse suite for the family at the posh Fairmont Chateau Lake Louise in Alberta, Canada, where they enjoyed the luxuries the sanctuary had to offer.

These included a private balcony, a huge king-size bed as well as beautiful views of the lake, Us Weekly magazine reports.

In honour of the special day, the 34-year-old singer posted a photograph of him and his little boy, who was wearing a onesie which read 'I [heart] Dad'.

Captioning the photo, he wrote: ''FLEXIN' on Fathers Day... #HappyFathersDay to ALL of the Dads out there from the newest member of the Daddy Fraternity!! --JT. (sic)''

The pair are said to be coping well with their new arrival but have hired help in the form of two male nannies.

A source said previously: ''She hired two gay male nannies she knows through mutual friends and is having them rotate schedules.

''He's [Justin's] in there too, changing diapers and gushing to everyone he knows that Silas is already 'a little angel.'''
