Taking to their Twitter accounts on Saturday, the loved-up pair shared romantic messages to one another, with Jacqueline tweeting: 'Hapy Valentine's Day @DannyO.'
And Dan let his girlfriend know he was thinking of her too, tweeting: 'Happy valentines day gorgeous.'
The couple have been through the mill a bit in the past 12 months, first off having the shock of discovering they were expecting their first child, before being plagued by split rumours.
At the beginning of 2015, Dan spoke out about the moment everyone thought the couple had split for good, when he tweeted: 'Relationships just don't seem to work.'
He later explained that he was just having a 'temper tantrum,' and that things were back on track for the pair now.
Their baby is due to arrive any day now, with Jacqueline looking positively glowing in recent pictures to her Instagram page. Could it be a Valentine's Day baby?
