Britney Spears got emotional in her latest Instagram caption as she revealed her two teenage sons - Sean and Jayden - have grown up so fast, and that 'time flies'.
The iconic songstress, 39, posted a snap with her rarely-seen two boys - who she shares with ex-husband Kevin Federline - on the social media site earlier this week, with the gorgeous family snap holding a heartfelt message.
The pop star is not often seen with 15-year-old Sean and 14-year-old Jayden, so some fans were surprised to see how they had grown and were now towering over 5ft 4in Britney.
The doting mother-of-two was ecstatic as she revealed her sons let her upload the 'cool edit' she had made to her Instagram page.
The trio posed underneath the sunset, looking extremely happy to be together.
Britney gushed: "It's so crazy how time flies.... My boys are so big now!!!!
"I know… I know … it's very hard for any mama especially a mama with boys seeing them grow up so fast!!!! Talk about enough to make you go to your knees... GEEZ!!!!"
She continued: "I'm extremely lucky because my two babies are such gentleman and so kind that I must have done something right!!!! I haven't posted pictures of them for some time cause they're at the age where they want to express their own identities and I totally get it....
"But I went out of my way to make this cool edit and guess what.... They're finally letting me post it!!!
"Now I don't feel left out anymore and I'm gonna go celebrate .... Oh s**t I guess cool moms don't do that ... Ok I'll just read a book instead!!!!"
Britney has come a long way since her early days, in which she had a bruising custody battle with Sean and Jayden's father Kevin.
This led to some of the lowest points in her life though they agreed on a 50/50 split on custody.
In 2019, this decision was reversed and the boys now spend 70% of their time living with their 42-year-old father.
The superstar has been at the centre of drama recently after a detailed documentary named Framing Britney Spears aired, giving fans insight into her conservatorship battle.
Since 2008, Britney's father Jamie Spears has been her legal conservator, meaning he has control of her finances as final say on a wide range of her personal life decisions.
Despite being unable to make major life choices, since being placed into the conservatorship Britney has embarked on two word tours, a Las Vegas residency and released four albums.
Last year, Britney filed an application to the courts to remove Jamie from the position.
However each of her appeals has been denied and Jamie remains as her co-conservator.
Britney previously opened up about her own personal battles on social media with a cryptic post, telling fans she's "allowing myself to not be so strong all the time" and that "it's OK to cry".
"On all accounts of the craziness the past year ... I feel like God’s tears have hit all of us with what the world has been through due to coronavirus," she wrote.
"This new year should be a year of cleansing our inner selves with meditation … prayer... any kind of hobby that brings joy… and being conscious of what we put in our bodies as well."
She added: "This all helps us to have a clear mind … body … spirit and offers so much more clarity in our everyday lives!!!! This year I devote myself to lots of tea and healing!!!! I'm working on allowing myself to not be so strong all the time and to know it's ok to cry!!!!
"I pray for deep healing this year for all of us and I hope we can all inspire each other !!!! Again … BE KIND - PASS IT ON AMERICA."
